Most devices showing up as "unknown device" in blutooth "add device" screen (Flex5)

Q: Most devices showing up as "unknown device" in blutooth "add device" screen (Flex5)

Note: Device manager lists appropriate bluetooth antennae. Some items are still showing up ok, but many (some new, some previously paired) are listed as unknown now, so they are useless to me until this is resolved. This is a fairly new Flex5 (bought at Microcenter about a month ago).I ran the Lenovo "Vantage" program to get the latest bluetooth drivers on board.Tried uninstalling BT driver and running manual install of intel and Qualcomm drivers. Windows10 is not seeing the Intel ones, I think as when I try to change the driver to the intel ones I only see the the QualcommAtheros and the generic bluetooth drivers available. I ran that installation a number of times, but havn't been able to try the Intel drivers yet. I'm not sure if they will fix the problem, but would like to try them, unless someone here can point me at something else that may be the cause. Thanks for any info!

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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 icon....it 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've been scouring the newsgroups for answers to the following problem and have tried everything suggested to no avail...

My USB 2.0 Pen Drive was working fine until yesterday. It now shows as unknown device and windows reports that it may not function correctly. It doesn't work at all!

However, I took it to work with me and (on a USB 1.1 PC) it worked well.

When I returned home, I tried again in my PC to no avail. I then tried uninstalling Root Hubs and Controllers and the like from Device Manager as suggested in many newsgroups and the thing sprang back into life. However, as soon as the
Enhanced USB driver is detected, the pen drive vanishes and the 'unknown device' returns.

I've been into safe mode, I've tried to delete the 'VID keys' from the USB section of the registry (which won't delete even though I log in as the administrator) and I've removed all USB devices and then uninstalled all hubs from Devce Manager and let them reinstall themselves.

I now have my Pen Drive working in (I assume) 1.1 mode by means of 'disabling' the 'enhanced host controller'. As soon as it is re-enabled I lose my Pen Drive and return to 'Unknown Device'.

XP says that my 'Enhanced Controller' has no problems.

Please help - everything was fine on Monday and a restore does no good at all. Why can I not delete the VID keys?

Thanks in advance,

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.

A: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.

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

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.

USB devices attempted:
1x Wired Mouse,
3x USB thumb drives
1x USB external hard drive

All devices are USB 2.0. The malfunctioning port is USB 2.0

My system:
Dell Inspiron 530s
Vista Home Premium x64
Motherboard Model 0RY007 (Socket 775)
Chipset Vendor Intel
Chipset Model P35/G33/G31

I clean installed an ASUS Laptop Model a2500h, Windows XP Home edition SP3.

There are two drivers that I can't seem to locate. The Hardware ID's are as follows.


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.

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.

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.

My seagate 2TB internal HDD suddenly crashed after a couple of days of weird loading.

The main problem I have is that the device is showing as Unknown Device on device manager. If i try to uninstall / Scan Hardware Changes, it just disappears. If I disable / enable, stays the same as unknown device. I reboot, and again it shows as Unknown Device but cannot do much. If I try to run any software to recover data, it won't see the drive so I cannot do it.

Device Manager:

SSD Drive (shows fine)
Another HD I have (shows fine)

Also if I go to disk management, it asks me to initialize the drive, which I dont want to do as I need the data that is inside.

I hope someone can please help me, Id greatly appreciate it (you have no idea!)

- I tried plugging it into a different PC, it didnt see it.
- I tried swapping cables with the other HD, no difference.
- Bios sometimes sees the drive, sometimes doesnt. Regardless of this, it behaves the same on Windows.

I recently upgraded to Win7 Ultimate (clean install) from XP 3/4 weeks ago, and for the last week or so am having problems accessing my USB external drive (although it worked ok at first).
When I connect the drive to my laptop, after a few seconds I hear a windows sound which tells me that the connection failed. In the meanwhile, the drive light displays solid for a moment but then begins to flash at a constant rate that seems faster than when operating normally and the drive cannot be heard.
I went into device manager and checked the properties for the "unknown device" and it was displaying 'code 28' stating the drivers have not been installed, but the last few evenings (after around a dozen or so attempts over several hours during each evening), the drive is somehow detected and is accessible.
I have also tried the following to try and solve my problem

- uninstalled the drive via device manager when displaying as 'unknown device' and rebooted. upon connecting the drive, windows tries to install the drivers but soon displays an error message stating that the drivers are not available.

- updated the bios to no avail

- went into disk management and refreshed drives to no avail
I also tried googling the device id when the drive shows as unknown (which is 'USB\VID_13FD&PID_1618&REV_0100') which brought up many results which seemed to include the line 'pnpdrivernotfound'
I would appreciate any help that anyone can offer, thanks in advance.

A:seagate usb external hdd - showing as 'unknown device'

Welcome to the Se7en Forums! FrEnZyUK

One suggestion given when buying any new external hard drive or flash drive often when simply being used as a storage device is to first reformat the factory Fat volume to NTFS for making it readily available. In 7 the support for Fat and exFat has returned allowing you to simply go into the Disk Management tool and assign a new drive letter for the drive. This will initialize the drive as part of the process making it available again.

If you have only a small amount of files and data on the drive presently you could simply elect to backup them up and reformat to NTFS while in the Disk Management at the same time as you custom assign a new drive letter. Windows will then remember the new letter that replaces the temp letter assigned when working.

With usb not so much eSata drives that are plugged in and unplugged often that will even be more of a help once a reformat is performed in automatically being reinstalled by Windows upon plugging the drive back in if unplugged at all.

Hi folks. I've installed Windows 7 on my Dell Studio Laptop. In the Device Manager, I have an unknown device showing, which reports as being Intel(R) ICH8M-E LPC Interface Controller - 2815Under System Devices, there is an identical device that has the correct driver installed. If I try to install the same driver for that device, the Unknown Device remains.I've also tried installing the following driverhttp://www.downloadatoz.com/driver/item_259290.htmlBut the device remains as Unknown.Can anyone help?My laptop is;Dell Studio 1735 : Intel Core 2 Duo T5750Graphics: 256 MB ATI Mobility RADEON HD 3650Memory Dual Channel 3.0GB (1X2GB + 1X1GB) 667 MHz DDR2 SDRAMHard Drive 250GB Serial ATA

A:Intel LPC Interface Controller - Showing as Unknown Device

I've already tried installing that Driver. Did a bit more digging and found out that it is actually the Infra Red receiver, and I've now installed the driver for it and the Unknown Device no longer shows.I installed the following driver for my machine.http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R190901&SystemID=STUDIO1735&servicetag=&os=WLH&osl=en&deviceid=17446&devlib=0&typecnt=0&vercnt=1&catid=-1&impid=-1&formatcnt=1&libid=17&fileid=262192I think the clue is in the Hardware IDsACPI\ITE8708, *ITE8708It's an ITE CIR receiver.

Recently got my new NVIDIA 780 GTX, 6 Gigs on board, DDR5 card. Was excited to get it installed. After a bit of time figuring stuff out I got it installed and booted up and of course it needed a driver so everything was quite LARGE for a little while then the screen flashed a few times and there it was.... Nice and normal looking.

Then I started running into issues. Like when I would reboot rather than just booting in I would be taken to my BIOS screen. I don't know why but I guess there is a setting there I need to adjust but don't know what it would be. I have a GIGABYTE X99-UD4 Mb. So if that gives anyone a one up as to what to suggest that would be great. I've tried rebooting a couple of times with the same result. Hangs at the boot screen, power off and power on, goes to the BIOS and then once I "Save and Exit" then it boots into my logon screen no problem.

Another issue is that when running the "Unknown Device Identifier 9.0" it's finding two instances of the video card. One is not highlighted but the other is highlighted in red. It's also still registered to my older GTX 760 so not sure how to get rid of that. I've looked all over but can't find where that older NVIDIA info is stored. Perhaps in my registry?

Thanks for the help..


A:New NVIDIA card showing two in Unknown Device Identifier!

In BIOS there should be a graphics setting to chose whether to use the integrated graphics or the dedicated card. It is worded differently sometimes like dynamic or static or something different. Anyway try to find whatever it is and change settings to see if it makes a difference.

Hello, While trying to update to the latest Insider Build of Windows 10 which is Build 15002, I was being prevented by a BSOD error on Update Installation(a.k.a The Green Screen of Death) So after some research, I found that I should make sure all my Drivers are updated. Upon going into Device Manager, I encountered that there was an Unknown Device, which meant there WAS a driver missing.  So I got the hardware ID here and am wondering if anyone knows how I could get the ZIP to this driver to update it: Hardware ID: ACPI\VEN_ASD&DEV_0001ACPI\ASD0001*ASD0001 Notebook Model: HP 17-p110nrOS: Windows 10(64-bit) Home Insider Preview Build 14986.rs_prerelease.161202-1928

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.

A:No audio device installed error and devices wont show in Device Manager

I see three different audio driver packages at http://h10025.www1.hp.com/ewfrf/wc/softwar...ct=3646926#N661.You need to find the right one to install. If you install one and the system doesn't work properly...please uninstall it before trying the next one.Installing the wrong one won't do anything harmful to your system...it just won't do any good to leave it installed.Louis

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..

thanks in advance

I have a blutooth speaker that I use with my laptop. When paired, the OS (Win 8.1) identifies it as headphones and uses the headphones icon. I don't like that; I want to give it my custopm name and use my custom made icon for this device.

When I change name and icon, all works as supposed as long as the device is not unpaired. But since I sometimes need to pair the device with my telephone, I have to re-pair it when using it afterwards with the computer. And then all my customizations are gone.

How can I get the OS to remember my device and apply the nice icon and name I have prepared for it?

OK so I have the asus rampage formula motherboard.

It comes with some utilities ... ASUS probe (for temp readings/voltages), AIBooster, and some other stuff.

The only one I installed was ASUS probe because I thought it would be useful, however, I'll get a BSOD randomly (even when not using the asus probe program) associated with the driver "ASACPI.sys" which when I look it up, is a driver for the "ATK ACPI Utility" (in device manager).

I remove ASACPI.sys from my system... now no more BSODs, but every type I restart the hardware manager comes up asking me to install ATK ACPI Utility...

I don't want it and can't permanantly get rid of it!

I even tried going to the windows\inf folder, found the oem.inf file that corresponded to this device, deleted it, and it still shows up. It shows up under device manager, under system devices, as "unknown device" every time I start my computer.

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.
The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.
The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.
Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.
I've tried:
uninstalling the device and rebooting
installing the latest updated chipset drivers from the dell website
windows updates
pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?

A:XPS 15 9550 Bluetooth stopped working (Unknown USB device - device descriptor request failed)

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.
After rebooting, BT and my mouse is now working again.
Something seems to be really flaky here, but hopefully this will help others with the same issue.

We have some symbol windows mobile-based handheld devices that we use in our business.  We connect these devices to our computers to copy files to.  This all worked fine until recently the devices come up as failed.
It appears in device manager with a yellow exclamation point.
Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.  (Code 19)
I've tried all the solutions I can find on the web and none of them work.
Uninstall the device in device manager and scan for changes.  It downloads the driver from windows-update and returns to code 19.
Tried hardware troubleshooter which basically seems to automate the process of uninstalling and scanning.
I've tried removing windows media player 12 feature and adding it back.
I've tried deleting USB controllers from Device Manager and rebooting, it re-detects them all and still gets code 19 on the device.
I've tried deleting upper and lower filter values in the registry which I found out later is mainly for CD/DVD devices, that didn't fix anything.
I've tried removing and re-installing Windows Mobile Device Center and driver pack and that did not fix it either.
Additionally Canon Powershot camera gives us similar results.  MTP USB Device failed.  
This is so far happening on 3 of our workstations that we know of.
At first we thought it was due to windows updates but nothing recent has been installed that looks rela... Read more

Thanks for posting in Microsoft TechNet forums.


Do you have Kaspersky installed? Kaspersky Filter driver caused that any USB device could not connect.


It is suggested to have a look at the following registry. Make a backup of it and remove the Upperfilters setting:


“Upperfilters” = klfltdrv


If the issue persists, please find a working machine and compare the registry settings.
