Solved: Dude! I don't get my Dell! No devices in device manager?! USB and sound don't work?!

Question: Solved: Dude! I don't get my Dell! No devices in device manager?! USB and sound don't work?!

Ok so I had to reinstall windows XP because my OS would not load and I got all the drivers reinstalled, diagnostic ran smooth and everything came up working ok etc but my device manager won't recognize anything! The compy says my audio mixers are not there, my USB devices are not working, hardware wizard is not responding, microsoft updates are not working, Dell's driver downloads are calling out for something that isn't there and I really really need this fixed ASAP so I can get to my external HD. So I tried putting an apple sticker on my Dell in hopes it would accept its new identity and start not sucking, but alas this did not work. If you help me fix this I'll seriously be your new best friend... I have apple stickers. ;-)

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

hi guys this is my first forrum with u guys so i would appreciate any help as i am stumped as to what is going on.

I have installed the drivers for my onboard sound and it is detected in the device manager list, but when you go to multimedia settings in the control panel, there is nothing under preferred device for output or anything. The mainboard is a Gigabyte RZ. i have had this problem before and i found a registry fix for win98 and ME to reset the preferred device list via the registry and it fixed the problem.

Thank you for any help.

There are no USB ports/links show in 'my computer', but they are visible in Device Manager .

When I plug my Thumb drive into the computer it tells me it's installed successfully. And also my USB mouse and webcam work fine. But there are no ports shown in 'my computer', which is strange.

What could this be, how do I fix it?
Regards, Joe.

Answer:[SOLVED] USB Devices not showing in 'My Computer' but are in Device Manager

Hi, make sure the USB device (removable device) you want to use is plugged into the computer then go to start search and type:-
diskmgmt.msc, open disk manager, if you have a mapped network drive you will find the USB device has been assigned the same drive letter. Right click on your removable drive and choose "Change Drive Letter or Paths..." and assign a different letter.

Open "My Computer" and the drive should be there. Next time you connect it, it will pop-up with a newly assigned letter.

Hi to all.

On my Dell OptiPlex 755 E6550 2.33, I've had intermittent issues with the headphone socket suddenly stopping working for quite some time,sometimes problem is auto detected and fixed, sometimes I download a driver or three to resolve. This time nothing is helping no matter what drivers I've tried. Have Win 7 Ultimate installed with just on-board sound. No sound or audio shows up in device manager? Are 755's fickle with on-board sound or just too many sound drivers installed? Any ideas please.

Answer:Dell OptiPlex 755 No Audio Output device and no Sound/Audio in Device Manager

There could be multiple hidden audio devices.
* Press windows key + R* Enter cmd, click OK* Type cd\ [press Enter]* Type set devmgr_show_nonpresent_devices=1 [press Enter]* Type devmgmt.msc [press Enter]* Once the Device Manager opens, open Sound and see if you have multiple grey out items. If yes, delete them, then restart the computer and retest

I have two USB audio devices that I cannot seem to properly install drivers for.
Focusrite Scarlett 2i2 & KORG MicroKONTROL

I am in communication with both product tech support teams but so far they have not offered a successful solution. As the same issue is occurring with multiple devices I thought it might be an OS issue.
I run Win 7 Home Premium x64

The problem is as follows:

The product drivers install correctly without error. However, instead of showing up in the Device Manager in either USB Controllers or Sound Controllers they both show in Other Devices with a yellow exclamation mark.
I have tried the following fix from this site (USB Driver - General Fix for Problems) and this actually enabled me to access a portable HDD that wasn't working, but it didn't fix the issue for my 2 audio devices.
I have also tried right clicking on the devices in Other Devices, selecting Driver Update. I then find the correct drivers listed but when I hit install I get the following error message on both:
"Windows found driver software for your device but encountered an error while attempting to install it. One of the installers for this device cannot perform the installation at this time."

Any suggestions would be greatly appreciated.

Answer:Audio USB Devices showing under Other Devices in Device Manager

Could it be the two devices are competing with each other and the driver installer gets confused? Details on the devices and the needs to use two of the same type probably would be helpful.

Hello everyone,

Laptop Samsung NP300V5A. Sound stops working about a month after Win 10 upgrade. No changes done at the time.

Audio devices show up under Device Manager, but not under Playback/Recording Devices. Same for Realtek Sound Manager - it doesn't see the devices. I can install, delete and update drivers under Device manager but it doesn't make any difference. It is not a physical problem, tested on Linux live CD.

Solutions tried:
-Installing various versions of HD Realtek Drivers (including windows update version)
-Installing/Removing Realtek software.
-Enabling/Disabling devices under Device Manager
-Called spirits of ancestors. Seemed like it worked for a while, but ended up being a joke.
-Did system restore to various dates.
-Restarted in safe mode
-Restarted various services such as Windows Audio, Windows Audio Endpoint Builder, Plug'n'Pray, Power, etc.
-Checked system, application and driver even logs.
-Tried a couple of registry fixes. Angered spirits of ancestors. Turning gray..
-Reinstalled chipset drivers
-Rebooted about 30 times
-Sound Device Troubleshooting finds no issues
-Display Disabled Devices is enabled

I've been looking for a solution to this issue for about a week with no result.

Answer:Audio devices in Device Manager, but not in Playback Devices

By what you have done, it suggests a Windows/sound corruption. Probably going to take a Windows reinstall. Sorry.

I'm trying to fix an hp pavillion dv6704nr laptop running windows vista home premium. It has the little red x on the speaker in the lower right hand corner. The owner said it has been there for some months. I have tried downloading the current audio drivers for the computer but every time I try to install the driver, I get an error that says the device couldn't be found.

The first time i restarted the computer, after the driver installation failed, the audio came back and worked fine, until I had to restart the computer. Now I keep getting the same error and nothing i have found so far online has helped.

There are no yellow triangles in the device manager and the device list isn't showing the category for "sound, video and gaming etc." at all.

Please help. I did a search but the other threads didn't solve this problem for me.
Thanks in advance.

i have installed the correct driver for this belkin bluetooth usb dongle model: F8T012XX1

but in device manager, it has the belkin device and microsoft bluetooth enumerator, which is great. but when u get further down the list. it has a tab named "other devices" and then a subtab with "bluetooth peripheral device" which has an exclemation mark on it.

i have searched for driver software using the update service but it cant find no update.

i have looked for the name of the manufacturer but found nothing.

i then disabled the unknown device, and sent a picture to my mobile phone. which confirmed that it was not the belkin bluetooth device. so i uninstalled the unknown device, restarted the computer. then when i logged in, it said that it had found a new device and wanted me to find the CD that came with it..

i would be greatful if any1 could help me on this..

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is. I decided to do another reformat on my hard drive. This time, I ignored the optional updates. I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

I was going to just flick through the similar threads, but I think my problem's slightly different.

The other day I got home and decided I needed to clean my computer up, so I went ahead and uninstalled about 20gb worth of games. Then I tried to install AVG, and it told me to restart my computer. When I'd restarted, no sound would come out of my speakers. I thought maybe something had disabled it in my volume control, but it wouldn't allow me to look at it. I tried going on Device Manager, and I got nothing at all in there. I thought it was maybe because I'd accidentally let themexp install WhenU onto my computer, so I got rid of it, and ran SpyBot, and let AVG do a complete Anti-Virus, and that produced no solve for the problem.

So I went ahead and reinstalled windows, which worked for a little while. Then it stopped working again. I want through your complete malware removal, and still no sound. I tried going through the BIOS and disabling the soundcard and enabling it, which didn't work. I'm pretty much at the end of my tether!

I'm running a DELL8400 with Windows XP. Thanks for any help in advance.

Answer:No Devices in Device Manager

So... you said you had no devices in the device manager, and then you said you fixed it. Does this mean that when the device manager was opened, it was just an empty, blank white window? But now it's not? Or is the only problem now that you have no sound?

I do not use a hub, since I have 3 ports free.But none of them show any signs of life - eg the scanner normally whirrs and buzzes for a couple of seconds after being plugged in which it now does not do and the web cam little "I'm on" light does not glow.I have been to the control panel->system->device manager. Here I normally find a long list of devices which reassures me amongst other things that each device is working properly. The device manager window is completely blank. Just a white space, no list - nothing, not even the name of the computer. I tried to restart in safe mode. After selecting the SAFE MODE option in what looks like an MS-DOS screen nothing happens at all - so I don't appear to be able to start in safe mode!So there are two questions.1) How can I get the device manager list back?2) What does a USB message about "hub port overloads" really mean?John

Two of the four USB ports in my motherboard were not working properly. After plugging in any USB device it would recognize something was there, try to find a driver for it, but fail at doing so. These are plug and play devices I had never had problems with before. The device manager said the SM bus was not installed properly. I reinstalled the chipset driver and that fixed one of the USB ports; however, one is still not working. When I plug in any USB Device there is no audible ding, no "this device is not recognized" pop-up, and it isn't even showing up as 'unknown device' in the Device Manager. I'm not sure what could be wrong.

I tried looking at the Universal plug and play service and when i double click it, it tells me configuration manager: the plug and play service or another required service is not available. The service however started and is automatic. Also doesn't matter which service I double click, it will tell me that message

Answer:Missing Devices in Device Manager

To view missing devices, close Device Manager. On the Systems Properties page, click the Advanced Tab. Next, click Environment Variables. When the Environment Variables screen appears, click New in the System Variables box.

You'll then see the New System Variable screen. Enter devmgr_show_nonpresent_devices in the Variable Name field and 1 in the Variable Value field as shown in the attachment below.Click OK to save the new variable and OK again to close the Environment Variables screen. Go back to device manager and your deviices should be showing again, plus a few extra hidden ones

Windows 7 64 Bit, does not detect ANY network adapters. We installed windows in August and it has been fine, now for some reason it simply doesn't detect any adapters at all and does not display a Network Adapters heading in the device manager folder tree.

The hardware in question is an onboard LAN card on a ASUS Sabertooth X58 motherboard, the lan card is listed in the bios as a RTL8110SCLAN

I have checked to be sure that the device is enabled in the BIOS, as well as disabling other on board devices in case there was some kind of conflict. I also tried installing an add on LAN card and that card is not detected either. I have also reset the bios and removed the battery etc. I have tried reinstalling the chipset and other drivers and I have uninstalled windows updates that happened near the time the network adapter vanished.

I used RKILL and ran ComboFix and Malwarebytes to clean up a few minor virus/spyware files. But that too has not helped.

Answer:No Network Devices In Device Manager W7

Hi, and welcome to TSF.

Did you read this ?


You should not run ComboFix unless you are specifically asked to by a helper. Also, due to the power of this tool it is strongly advised that you do not attempt to act upon any of the information displayed by ComboFix without supervision from someone who has been properly trained. If you do so, it may lead to problems with the normal functionality of your computer.

Did you try to run the add new hardware wizard to see if it detects the card ?

After uninstalling and then updating my graphics card drivers, I decided to plug in an external USB hard drive into one of my USB ports. Windows XP Pro notified me that new hardware was found:

other PCI Bridge Device
PCI Memory Controller
SM Bus Controller

Consequently, no drivers could be found so now under ?Other Devices? in Device Manager, these three devices are shown with a question mark and exclamation point.

Obviously, I need drivers for these devices. Do I need to install drivers for a Lacie USB hard drive? Or does this have something to do with what I did with my graphic card drivers?

Thanks in advance!

My PC (Windows XP) has a problem -- in device manager, all of the imaging devices are in broken state. They are listed under imaging devices, but they have the dreaded yellow circle and question mark on them.

This began to be a problem only fairly recently, with my scanner. Can't scan; get an error message. This is true despite replacing my previous scanner.

In Device Manager, the properties screen for the scanner (as imaging device, it's a multi-purpose and is working fine as a copier and printer) says:

"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click troubleshoot etc."

I've been through the whole troubleshoot menu, with no results. Also been on the phone with HP tech and did the whole uninstall and reinstall thing (again) and it did no good. He told me it's a PC problem and I need to ask Dell about solving USB controller or BIOS issues.

Anyone have any idea what is going on inside my PC, and how I can go about fixing this? Thanks for reading and any advice.

I recently uninstalled a usb logitech headset and tried to put my old analog headset back in and it would not work. I then detected through view on device managers the invisable driver and also uninstalled it. It still will not work and when I do a driver detector scan I still show having

"USB Composite Device - Logitech USB Headset"
"USB Mass Storage Device - U3 Cruzer Micro"

They are under "Unplugged Devices".

I am using a trial version of Driver Detective to find these and don't want to buy it. So I was wondering if these two(for sure the first one) need to be uninstalled before I can hook up another headset how else could I go about uninstalling them? Or would another usb headset just install over them without a problem?

Answer:Device manager hidden devices.

If you have uninstalled all of those, and;

You don't have anything else from Logitech/Cruzer,
just go to Start->Run->Regedit
then Edit->Find->Find next

Delete everything.


No problem is so huge (in these small spheres) that it couldn't be solved with free software.

So never ever go buy anything unless you area SURE it is exactly what you need.

Answer:Extra devices in device manager

That occurred with my ATI 9600 .All I did was delete both in device manager ,then reboot ,Cancel the auto-reinstallation by windows and use the Hardware Wizard to install your drivers.You choose the drivers you want installed from a fie or disk.
ATI websays you can also do this by using the Update driver tab in Device manager and and again force Windows to use your drivers.
There are 2 instances of My 9600 in device manager because it supports more than 1 Display(Digital,Analogue) It is probable the same for you.

Answer:Unknown devices in Device Manager

If it is a new unit this should not happen. Did you cut the factory tape on the box? Maybe someone altered something?As far as fixing it. First try pressing the blue button at system startup and restore to factory defaults. If that doesn't work call Lenovo and tell them about it.You could go get unknowndevices, run it and it will give you a clue as to what the unknown devices are. Then go get the drivers and install them.

I know ASUS often has utility programs that show up as drivers, for example I had the ACPI\ATK0100 which was listed as an UNKNOWN DEVICE, and I installed that utility fine.

I am just not sure about the other two. I was told on another forum that it could be something to do with the sound drivers, but I suspect it is one of ASUS' little utility programs.

Any help would be appreciated. Also if any additional info is required, let me know and I will post it.

Since installing WP Pro SP2 on my laptop I've noticed 3 big yellow question marks in device manager for Network controller, SM Bus controller and Video controller. Despite these problems I can use the laptop as part of a network and video display seems OK until I try to video edit on Avid, which refuses to display moving video and flags up a warning about the video card.

I've been trying to re-install the driver for the ATI mobility radeon 9000 (64MB) adapter and get an error message that an INF file is missing and to try installing a standard VGA card.

I would recommend to download Lenovo System Update that should fix most of the missing drivers. If you still have any missing drivers after updating the driver with system update you could post again, but i'm sure the list should be shorter then. You can find system update here: 3.14 is for XP) Optionally you can download and install each driver manually from here: you system and you should be given a list of drivers for your computer. Since you didn't specify the type/model of your T61 i couldn't give you the correct direct link) - "biometric coprocessor" is the fingerprint software- "network controller" might be the wireless adapter- "pci memory controller" should be fixed with the chipset drivers i think- "unknown device" need the hardware ID found in device manager to say what this is- pci device could be the Intel AMT driver or modem drivers....not 100% sure -gan

When Windows is configured to show ghosted devices (non-present devices) it shows a number of missing devices - at least on my machine. So my question is how to decide what to remove in order to improve boot time?

I've managed to figure out that the Avast legacy driver entries are okay to remove along with a few other entries that were related to previously installed software. It seems that Avast's own aswclear removal tool left them behind!

Anyway, currently system restore is disabled on my machine (I make system image backups) and I see numerous entries under "Storage Volume Shadow Copies" and "Storage Volumes" - is it safe to remove these? Is there any way that "Storage Volumes" could be related to encrypted drives?

Answer:Remove Ghost Devices - Device Manager


I decided to remove non present devices - other than system devices and a couple of non plug and play devices. Rebooted and everything is ok.

Storage Volume Shadow Copies has vanished but under Storage Volumes - Generic Volumes re-appear when new drives are connected.

I've been advised to remove all USB devices in Device Manager but my system just hangs when i get to the last device. I have tried disabling devices in BIOS and then removing them but with the same result.

I have a problem installing a Plug and Play hub which has led me to this course of action. See previous post.

Any further advice greatly appreciated.

I have a Equium L20-198 PSL2ZE!

I'm having difficulty with the drivers provided by this site whenever I try to install the driver it stops telling me that the chipset is unsupported by the program, so I have these unknown devices left to resolve

ethernet controller
pci modem
sm bs controller
sb controller
vga controller

And even though there a wireless switch (and it works ie turns the light on). I have no software or details of the wireless device installed (its standard) whatever that is!!
Is there no driver utility as in all the drivers in one from toshiba!

Thanks to whomever repiles in advance because this is driving me mad!!

Answer:Re: Equium L20-198 - Unkown devices in device manager


What OS did you install on your Equium L20??

Normally you can download all drivers on the Toshiba website. Did you check this? => Support & Downloads => Download Drivers

I had a similar error message if I tried to install a newer chipset driver but it worked if I installed the driver in device manager with the advanced installation order.

Running Windows 7 Ultimate, 64-bit on a Dell Latitude E6500.

There are three items under Other Devices in Device Manager that have cryptic names and seemingly no drivers available from Dell.

Broadcom USH
PCI Serial Port
PCI Simple Communications Controller

I have installed many drivers and some install successfully with no change in Device Manager or I get an error message the driver is not for this system.

Can someone point me in the right direction on these devices.

I am having a slight issue with my new setup, appears to be driver-side. Every time I restart my computer a window pops up stating that a driver could not be installed for "IDE channel." This box appears six times in which I have to close out. There are six of these "IDE channel" devices listed (under IDE ATA/ATAPI controllers) in the Device Manager w/ the little (!) next to them. When I go to install a driver for each of the devices I get "driver is not intended for this platform" or something like that. I don't know what I should do because I'm really not sure what I am looking at exactly. Any help with this would be greatly appreciated.

Also, I've installed all the drivers for my motherboard, graphics cards, and sound card ...all of which work fine. In the Device Manager, I am also seeing two "PCI device" and a single "Unknown" device. The only PCI card I have installed is the Sound Blaster and I installed the drivers for that; it works fine. No idea what the "Unknown" is...

Does anyone else have these two Unknown Devices in their XPS 13 device manager? I don't recall removing anything that would cause this and the system can't find any device drivers for it nor does updating the drivers from the dell web site resolve it. There isn't any current function that we're using that isn't working so I'm not sure what category of thing these are and the hardware ID's aren't of the expected format so they don't reveal anything either.  Everything is unplugged and wireless is turned off(airplane mode on) so these are not external items.

With my audio manager I can't adjust any settings in the properies since it says there is no sound card. I STILL Get sound though.

Hello; Pictures are enclosed and marked accordingly on the bottom

Working with Windows 10 Pro Version 1703 OS Build 15063.483 64 Bit x64-Based Processor

I have a unique pain in the butt.I built this PC in 2011, and have had no problems with it until April.

2 Reinstalls of Windows later I have come across a problem.

My motherboard has Bluetooth built in and before my April incident it always showed in the "Device Manager", it also showed in the "Action Center" on desktop.

I always shut it off or just shut off the display of it, I had no use for it.

Now 3 weeks ago I finally came into the 21st century when I got a cell phone.

The cell phone has Bluetooth and playing around with it I got it working on the phone, when I went to Settings in Windows to "display" the Bluetooth in the "Action Center" I can not find the switch for it.

The only thing that looks like it is a "Connect Button" (see picture)

When I open "Device Manager" the "Bluetooth" icon was not visible.
Now I looked at my "Device Manager" during the week of March 13 - 18 a couple of times and the "Bluetooth" was there.

When I click on the "View Button" and scroll to "Show Hidden Items" the "Bluetooth" comes to view and has the drivers installed.

When I check the "Properties" General Tab I get this;

Currently, this hardware device is not connected to the computer.

Whenever I connect a bluetooth device to my PC (such as my phone) I always get this list of peripheral devices with yellow exclamation signs (see attached image).

I have tried right-clicking on them and choosing to update each one, but that never works. I have also tried deleting/disabling them and they always come back.

Any advice on how to fix this would be appreciated.

Hello, everyone.

I noticed a problem in my keyboard recently, but i'm not sure if it's really on the keyboard, and might be in the windows or software related. The problem is that the keyboard randomly starts freezing, it's hard to explain with words, basically the keys do not operate in the way they should, i notice this problem usually when i'm playing games, where my "W" that should move my character forward continuously. does not, instead of doing what it's supposed to do my character goes forward while freezing along the way. When i unplug, and plug it again on the USB port, even on a different one, the keybord start to operate normally again, but randomly shows this problem from time to time. It's not only with the "W" key, was just an example.

I noticed something yesterday, i don't if it's supposed to be that way, and i can't find any information about, it's that on device manager it shows multiple devices on the keyboard section, when the device is connected, as it shows in the image below:

One more thing, is all of them looks like the same thing, but i'm not sure if they really are, image below:

If i uninstall all of them, except that one that i marked with purple, he is the 4th one in the first image, the keyboard still operates, i'm not sure if the problem is fixed by that, cause it does not happen all the time.

Now that i described everything, i want to ask 2 questions:

Hello there,

i am trying to install a webcam for my friend. Every time we try to donwload the software to install the thing, it installs and then says that there is no webcam detected.

I have tried all 5 USB ports, reinstalled the driver 7 times through web and CD. Have bought two new cameras. Have done everything under the sun and now i ask for your help.

I think the problem is that Imaging Devices isnt a catagorie. The webcam (Creative Live! Vista Cam) is on 'Other' section of device manager. When i go to repair it, it completes and calls the driver Composite USB Device. if i close this and re-open it, it says the error again.

What can i do for help!

Thank you for your time

Answer:No imaging devices catagorie in Device Manager

There won't be an Imaging Devices section until an imaging device is installed properly on the computer.

It sounds like the USB ports aren't working correctly or the drivers have an issue.

You are installing the software before plugging in the camera right?

Also what version of Windows is on your computer?
