I've been having this issue for weeks now.
I have a Logitech mouse on an Asus x571GT laptop, and one day the Bluetooth connection to my mouse suddenly disappeared.
I checked and the Bluetooth on my laptop disappeared. I checked DEVICE MANAGER and the Bluetooth was gone (unless I selected to show hidden devices) but under the Universal Serial Bus, one of the drivers is called "unknown usb device descriptor request failed" appeared.
If my Bluetooth is working, that error isn't there. The second my Bluetooth disappears, "unknown usb device descriptor request failed" appears under Universal Serial Buses dropdown menu.
I've searched online and...
3) I've uninstalled "unknown usb device descriptor request failed" and restarted the computer. Sometimes the Bluetooth returns and everything is fine for a couple of minutes/hours/days before it suddenly disappears again, and "unknown usb device descriptor request failed" driver reappears
Before, I did not.
But I did find one solution where I had to add the 'unknown usb device descriptor request failed" into the registry, unplug the USB device, power off, and while it was powered off, I disconnected the Power adapter from the laptop. Waited a minute or two, and plugged back in the power adapter, powered it back up, and once I relogged into Windows, then plugged the USB back in.
So far, it's working.....
So far....
uninstalling the intel bluetooth software from "Programs and Features" where you would uninstall software, as opposed to uninstalling device drivers from "device manager" is what solved this problem for me. i uninstalled the software that way and installed the drivers for the bluetooth from my motherboard manufactures website fixed it.
Believe me, I tried EVERRRRRRRRRYTHING.
The latest solution I just tried was selecting the 'unknown usb device descriptor request failed" and adding it to the registry and restarting the computer.
I just did it 30min ago, and so far it's working.
But with this 'unknown usb device descriptor request failed" sometimes it works for a few minutes, hours, days before it crashes.
Hopefully this solution works
If your operating system, BIOS, and drivers are up to date and the issue persists even after performing a full power cycle and uninstalling the intel Bluetooth software from "Programs and Features", the last steps would be to check this issue with Asus since they may need to run some tests on their laptop.

In order to resolve this issue, your device or any other devices you want to connect with this same issue, I suggest you do this; Open the Windows PowerShell (Admin) and type: chkdsk /f/r/x. It will inform: 'The type of the file system is NTFS.
Cannot lock current drive.
Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)' select Y then re-boot your machine and follow the on screen prompts.
After the reboot, again, Windows PowerShell (Admin) and type: sfc /scannow and allow the process to finish.
Now clean the registry with a reputable program such as CCleaner then take a note of the device/s name and select 'run' from the Windows menu list bottom left.
Type 'regedit' without the apostrophes and open the registry.
Select 'Edit' then Search... and type the brand name of the device in the search bar.
The search results will point you to a series of strings of the device that was giving the *(device descriptor request failed) code 43* error message.
Every string in the registry with the name of your device will need to be deleted but ensure it is the device's name from which was generating this error example; Logitech, Seagate, whatever brands device name that has generated this error code!
Ensure you have removed every last trace of your devices name in the registry.
Then after completion use the CCleaner again to remove all known traces and re-install the devices software if this is the case.
Your device will come back to life without the error message and start to work again.
Reasons why this happen are not entirely certain but often PC's pick up spyware/malware/virus's and corrupt the registry's strings other times, updates and upgrades in particular over lap information and again, corrupt the software and its registration process.
Selecting "USB xHCI Complaint Host Controller" the same issue but shows the "Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)" on device manager. Selecting "Chipset Controller" installing the Chipset Controller on the device manager but the propery shows that "No drivers are installed for this device" . But "Unknown USB Device (Device Descriptor Request Failed" disappears but placing USB, the USB is not found.
Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point first.
As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
I am using Win10. Has anyone had any trouble connecting a NanoVNA2 v4 to a PC? I get the following USB error under Device Manager if I connect the NanoVNA before starting the QT software:
Unknown USB Device (Device Descriptor Request Failed)
When I click on that description it says:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
I tried multiple computers and see the same error. I even tried to manually install the Cypress driver as Serial USB device since Windows was finding some Microsoft driver initially. Then, I get rid of the USB error and the QT software sees the COM port. I select the COM port but the QT gives me this error:
xavna_read_autosweep failed: Resource deadlock avoided
Nothing seems to work. The VNA has an operational screen with the traces and menus. I cannot use the windows software anymore due to a USB error. Any suggestions? Do I need to JTAG or whatever with the STM? Where is that process and the pin locations documented? Can anyone confirm the Cypress driver hardware type: Serial USB?
Thanks,
Mike
Only the QT software is officially supported and tested with every firmware release. NanoVNA-Saver v0.3.9 is known to be buggy; see if v0.3.8 works. Check if another program is trying to write to the serial port and try a different PC with Windows 7, Linux, or Mac.
"I have a 64GB USB flash drive that I haven't used for about a year. Now I constantly get a massage saying that the device has malfunctioned. Device Manager shows a similar massage. I formatted the USB drive twice now and still get the error. I tried unplugging and plugging the device, but nothing changes. I cannot find any further information about the USB drive in Device Manager except the hardware ID is USB\DEVICE_DESCRIPTOR_FAILURE. What should I do to be able to access the USB device properly?"
Your USB device cannot be recognized or reports device descriptor request failure error in Windows 11/10/8/7? We use USB devices all the time and it is quite frustrating when it is malfunctioned, not working or not recognized in Windows. The USB device_descriptor_failure is one of the issues we often encounter. In this article, you can find 9 reliable solutions to fix the problem and make your drive work again.
