Bluetooth Device Missing, Unknown USB Device

Q: Bluetooth Device Missing, Unknown USB Device

Recently I attempted to connect to an existing paired connection to my phone via bluetooth. I have never had this problem before, yet suddenly Bluetooth is missing. There is no longer an icon in the taskbar, the setting in "PC and Devices" is missing, and there appears to not be a driver installed, rather, an ""Unknown USB Device (Device Descriptor Request Failed)" appears in my devices instead. I have taken many steps to attempt and fix this, such as:
manually starting Bluetooth services from services.mscuninstalling the "Unknown Device" driver, then attempting to let Windows reinstalldownloaded the driver software from Lenovo for the Bluetooth adapter, installed it manually restartedtake a system restore created yesterday and revert back to it

Everything else in the PC functions perfectly. Any help is appreciated

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.)

A: Bluetooth Device Missing, Unknown USB Device

I had a similar problem recently where my bluetooth seemed to have just disappeared.
I ran the Find and Fix problems with devices (Just typed it into the start screen). It found one thing which by memory said something about a usb device being disabled. Clicked for it to fix the problem and enable it. Sure enough my bluetooth was right back.
Not sure if it will work for you, but its worth a try.
Good Luck

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.

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

I get crazy with this problem. I think since I installed the Windows 10 Creators Update, my Bluetooth connection to my Microsoft Surface Keyboard (Bluetooth) gets lost. After that the Bluetooth is shown in the hardware manager as an "unknown usb device" (Error-Code 43). What helps: Deinstallation of this device, shut down of the laptop and than turning it on again. After that Bluetooth is installed again...until it randomly breaks down like described above. Sometimes it loses Wifi-Connection too when the Bluetooth breaks down. It just happend when I work with the above mentioned Keyboard. When I work remotely with an MS Sculpt Bluetooth mouse, I never have this problem. Not driver re-installation helped. Wifi/Bluetooth card replacement also didn't help. Do I really need to reinstall Windows 10 or throw the Keyboard into the trash? Hope someone can help me here.

The bluetooth icon is gone from the taskbar, and it's missing from Settings/Device.

I can't hook up my external bluetooth speaker. I was able to as recently as a few days ago.

I recently plugged in a bt dongle for a wireless mouse; but I'm almost sure I've used the bt speaker since then.

I paired Microsoft Designer Bluetooth Keyboard and Mouse to my Windows 7 Professional x64 HP ZBook 14 which is connected to my company's corporate domain. Everything worked beautifully until they had to re-image my PC to resolve a disk encryption issue. That issue is resolved, but I have had bad luck getting my keyboard and mouse to pair and remain connected ever since. However, that's not even the problem now. After troubleshooting my Bluetooth issues by installing different driver versions, pairing and un-pairing my keyboard and mouse, changing settings in Bluetooth Support Service and more, I now have two Bluetooth Peripheral devices that always appear in Device Manager. I believe these are remnants of previously paired devices, but I can not get rid of them no matter what I try. These devices do not show up in Devices and Printers, they become Bluetooth Low Energy HID Devices when I install the computer manufacturer's drivers... As I typed this I thought of installing the Intel Bluetooth drivers I had previously installed to see what would happen... Ok that made things worse. Now there are three random Bluetooth Low Energy HID Devices and none of them are actual devices that are paired to the PC. And pairing the devices does not help. If I could, I would just delete the registry keys but I can't (remember, corporate domain PC). Any help from you brilliant people would be great. Thank you!

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 have no idea what a Bluetooth Peripheral Device is. I took some screenshots of the messages I receive every time a wake my computer up or turn it on. (1st, smaller picture)

It tries to update a driver but always fails and gives me this. (2nd, larger picture)

Hi all.

I'm using an ASUS laptop X53E series running Win7 sp1. I use an Acer 27" external monitor and do not have the laptop monitor on. I noticed an error msg this a.m. indicating that an Unknown Device is missing a driver. I searched in "Unknown Device Properties" -- "Details" -- "Property" -- "Device Instance Path" -- "Value" to figure out what device is being detected. The Value is ROOT\DISPLAY\FSVIDMIR.

I haven't found anything by searching Google, Bing or Tech Support Guy. This "unknown device" was installed six days ago on 8/30/14. I did change the monitor connection from HDMI to a VGA 15 pin cord, but that happened yesterday, not six days ago.

I should also mention that I connected my Samsung Galaxy 3 to a USB port which screwed up my system (I don't remember any of the details) but that was well before 8/30/14. I cannot open TSG SysInfo or I would have included it in this message.

Any ideas, direction, etc.

Thanks in advance,

Where can I find the missing drivers? 2) The second problem is probably related to the first.Everytime I start the laptop I get a usb device sound right after the startup even though I don't have anything plugged into the usb ports. So I'm guessing it's trying to connect to the peripheral devices... Did anyone here have the same problem or can help me solve this? Thank you in advance! Kind regards Jens

A:Lenovo G500s Bluetooth Peripheral Device Drivers missing

hi Jens,
Welcome to the Lenovo Forums.
Regarding your concerns:
1. From this link  that hardware ID is pointing to a Bluetooth Hands-free Audio Gateway by Broadcom.
Since you already installed the Bluetooth driver, can you try one of the following:
a. Navigate to the C:\Drivers\Bluetooth\Broadcom and run the setup.exe file to re-install the Broadcom Bluetooth Driver
b. Follow this guide on how to manually install the BTHENUM device driver (point the driver to the  C:\Drivers\Bluetooth\Broadcom folder).
c. Install the WIDCOMM Bluetooth Software
2. If you have a bluetooth headset / speaker that was previously connected before, it's possible that these devices are automatically pairing themselves to the machine everytime you restart. Try to check if installing the Bluetooth driver in problem #1 resolves the issue.

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!

My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time).
All drivers are up to date.
In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem.  There is no other touch screen device showing in device manager. 
How do I perminently solve this?

So should I do this:

When I download that zip file from under "Install the Bluetooth driver:" it has so many files to choose from.... I don't know what to do?

I've also found out that I need to disable "boot from network" or "boot from lan" in bios to get rid of this unkown device issue?

Well it might be a good idea to look at the following tutorial:

Use the link in Step 7

Also I tend to find this tool useful:

Right click on each result in the list for more options.

Edit: On my machine a similarly named device appears to be a webcam.

In the list USB Composite Device doesn't mean much but matching the ID seems to indicate that it's the webcam.

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.


A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more

A:Unknown Device - Device Instance Path (ACPI\INT33BD\1)

Hi: I am pretty sure you need this driver.  The latest is for W8.1. This package provides the driver that enables the Intel SidebandFabric device. Intel Sideband Fabric Device Driver is a bridge tothe Intel Dynamic Platform and Thermal Framework. This package isprovided for supported notebook models that are running a supported operating system. File name: sp65474.exe I don't know if not having that driver installed is related to the black screen issue.

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

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 have Windows 7 Ultimate. Since very recently an unknown device keeps popping up in the device manager every time I start Win. It's reported location is within the front USB root hub but I haven't changed there anything lately. The device status reports "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall/disable it but it will get picked up again the next time I reboot. All other usb devices (mouse, keyboard, web camera, APC UPS, external drive, printer) work fine. How do I get rid of this nuisance so that it doesn't reappear?

Just bought a Satellite M50D-A-10L and after 1 week, the HDD failed. Of course, I had to replace it on my expenses, because warranty would do so in about 2 weeks, which was too long to wait for me.
Anyway, I've lost also the preinstalled Windows 8.1 but that's not a tragedy, because I reinstalled it and everything is working fine.
The problem I have I that one of the drivers is unrecognized by "Device Manager". The device is named "Device ACPI". Any idea what missing driver is all about?
Thanks in advance for your answers.

PS: Not sure how to attach a screenshot of "Device Manager" with missing driver...

driver not installed on unknown device.
the chipset driver has been installed and I can't figure out how to find and install these two drivers.
Any help appreciated.

A:missing universal serial bus driver and unknown device

You missed one, download them all again and go one by one.
If you're able to extract the actual Driver files directly then just naviate to it from the Device Manager and update.
Things like these are tricky at times and require lots of manual work. Create one folder with all the drivers and start opening them one by one. Then move them over to another fold once you're finishied.
I like to download them and name them what they actually are. Makes it easier to track.
