Bluetooth just died

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi.

Yesterday I was sending a few pictures from my phone to PC via BT but in the middle of the transmission BT just died (icon disappeared from the Windows taskbar).

Today, I checked on Linux and it wasn't there either.

I went back to Windows and in Device Manager there's no Bluetooth anymore but there's an item with the exclamation mark:

"Unknown USB Device (Device Descriptor Request Failed)"

I suspect it is involved but I can't be sure.

Anyone knows what it could be?

I searched a little on Google and found that it might be a FAULTY HARDWARE!

How could it had happened if it was just working?

Temperatures inside my case are not excellent but they're not bad at all.

I'm just posting it here because the BT is integrated to my ASRock B550 Taichi.

Regards

	For those who happen to face the same issue, I hope this helps you: You'll find some attempts to fix this in Google/Youtube but none will work (maybe I just didn't find the right answer). The steps I did that solved it: 1. In Windows Device Manager, uninstall the problematic USB device/driver; 2. Uninstall the BT drivers; 3. Restart and go into BIOS/Setup; 4. Find where you enable/disable onboard components and disable BT (I disabled the main wireless controller, so I disabled BT and WiFi); 5. Let the computer boots Windows normally then reboot again; 6. Go into BIOS/Setup and re-enable BT; 7. Boot into Windows and reinstall BT drivers; 8. If the it doesn't appear in Device Manager, reboot; 9. Check if the BT appears in Device Manager (but you'll know it came back when you see the BT icon in the taskbar). The headaches are gone. Regards

	I made an account just to thank you for this. Your steps worked. I followed them exactly, but i think turning the device on and off in bios may have been all that was necessary. Still, doing so would not have otherwise occurred to me. Thank you very much.

	This did not work for me I disabled the WAN in BIOS because I could not find any bluetooth. Have seen other suggestions to reset CMOS. Most problems I have had with a brand new motherboard in 20 years... The tech support options from this brand are very limited.
