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. |

Hello, I found this post, I'm having a similar issue. After I updated my GPU drivers, BT has suddenly disappeared. There is no bluetooth in the device manager list, nor among windows services. It's like my hardware doesnt support it at all. There is also a notification about the last usb device that has not worked properly. I tried to followed the steps, uninstall any suspicious device, enable BT inside the bios, but its still not working at all. I'm using a B650i Lightning wifi with 7900x3d. Any help would be welcome. |

those issues are dependant on a wireless card used in your system and actually os used.. (windows sets flags for cards making them unusable until power down. ) list the specs :) ------------- asrock b650m-hdv/m.2, ryzen 7700x@85watt, arch/kde |

I'm having the exact same issue, my Bluetooth was working fine, suddenly it doesn't work, I have also recently done a Nvidea driver update. Interestingly the Wi-Fi still works fine. What I did originally; - Install bluetooth driver direct from ASRock "MediaTek_Bluetooth(v1.1037.0.424)" What I tried after it stopped working; - Re-install with existing file I had - Re-download in case somehow there was corruption during the download, unlikely but takes a few seconds to check - Check Bluetooth is enabled in BIOS - Full power reset (unplug power supply and hold power button to fully discharge for 30sec, then reboot. I noticed many devices were listed as 'unknown' in the device manager. Bluetooth was hidden but visible if selecting "show hidden devices" - The drivers were there but saying that it was not plugged in. My case has not been moved or opened during the time that it was working vs when it stopped, I doubt that anything came lose internally. As for the specs; Windows 11; ASRock X870 Pro RS Wifi Wifi module used R717 Other specs (Doesn't seem relevant but you never know) 5090 9800x3d 32gb 7200mt RAM PCIE 5 M.2 2TB storage. My BIOS is at at the base version from when I bought it, I've been reluctant to upgrade as I've seen there's been a few issues with ASrock drivers, some relating to DRAM OC and others relating to 9800x3D (Specifics not known here, but reports of damaged CPUs - Unlikely but was sitting on the side of caution). However, there was a new BIOS update 1 month ago so I might try it. |

That's why I use Linux - it has fewer problems. If you ever encounter an issue, you'll be fixing the problem directly rather than using a workaround. For example, I wrote a systemd service to disable the Mediatek MT7922 driver in my laptop when the PC goes to sleep, which solved all the card's issues without needing to restart my PC. edit: not to mention i dont have to look for drivers downloads, because these are included in the kernel/firmware

| I discovered something interesting: Mediatek MT7922 on my X670E Steel Legend suddenly stopped being detected in Windows, but when I booted into Linux it was recognized immediately and worked flawlessly. Good grief... |

| Just wanted to check in that I recently had this problem on my X870 Riptide WiFi - the BT just stopped showing in the list of the devices on both Linux and Windows - nothing was helping including reloading bluetooth and wifi drivers on Linux in any order - and it just reappeared as soon as I updated BIOS to 3.26. |
