[SOLVED] Bluetooth stopped working, kernel having trouble with its USB

Since yesterday or the day before, Bluetooth on my desktop machine has stopped working. The machine also seems to be taking more time than usual to start up, probably because it gets stuck here for a minute or so (taken from journalctl):

 2月 26 12:47:34 archlinux kernel: usb 1-8: new high-speed USB device number 3 using xhci_hcd

Indeed, the Bluetooth functionality doesn't appear in lsusb:

$ lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

but the Wi-Fi part of the same module, a MediaTek MT7921K, does appear in lspci, and is functioning correctly:

$ lspci
...
08:00.0 Network controller: MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz
...

Things that might be related are the motherboard firmware I recently updated, and possibly some package updates, though I'm not sure which, if either at all, has caused it. Is this maybe a bug somewhere, or have I misconfigured something?
I did make sure that Bluetooth functionality is "Auto" or "Enabled" in UEFI settings, and nothing changed between the two settings. I even tried "Disabled" and the same message appears in journalctl, so maybe the setting doesn't actually hide it.
The CPU is a Ryzen 9 7900X, and the motherboard is an ASRock B650M PG Riptide Wi-Fi.

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

That looks like a hardware problem to me.  It has the look of a bad cable.

I don't think this is the issue, but verify that the version numbers reported by pacman -Q linux and uname -a match.

Uh oh, I sure hope I won't have to RMA this motherboard. The Wi-Fi module that provides Bluetooth is something like an M.2 card I believe, so any connection problem would be on a circuit board.
I'll just wait for the next firmware update, since ASRock seems to be updating it every other week or so. At the moment I only use Bluetooth for my DualSense, so I can just use USB for that until the Bluetooth gets fixed.

And yes, pacman -Q linux and uname -a match with 6.1.12.arch1-1.

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

Oh, nevermind all that. Looks like you were right about it being a hardware problem, so thanks for pointing me in that direction. I turned off the main power switch on the power supply, and after leaving it off for several minutes then turning it on, it's all working now. No long startup anymore, and my DualSense connects via Bluetooth just fine. Perhaps the module relied on standby power, so it never got fully reset after having some sort of problem.
I think I had a similar issue with a laptop I had in the past where fully disconnecting power fixed it, even though it was on Windows 10 and with Wi-Fi instead of Bluetooth. For the record, in that case I think it involved something like disconnecting the battery if it's removable, or if the battery isn't removable, holding down the power button for a very long time.
Anyways, marking this as solved!

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

Any chance that happened right after you had used Windows?   Is Windows "Fast Boot" enabled?  Are you sure?  Microsoft has a bad reputation for silently turning it on after it has turned off by users.

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

Nope, I've only used this machine with Linux. No dual boot.

Unsure what the etiquette here is regarding necroposting. Didn't read anything in the Code of Conduct about it and thought it might be useful to someone who comes across this down the line to hear that this post helped me.

I had the exact same issue over two years after this post was made after pulling a kernel, firmware, and microcode update in one command. Like the OP, I had to shut down completely and boot back up for Bluetooth to start working again.

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

I don't know if it was wrong, but it helped me. Who knows how long I would have chased my tail before shutting down, but bluetooth worked again after a shut down and seems to hold on restarts. Note for others : I did an update that included mediatek(my laptops combined bluetooth/wifi controller), on the restart the bluetooth was down:
bluetoothctl show
No default controller available

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

I had the same problem. It was an Acer Swift3. Bluetoothctl returned no devices, and dmesg returned an error about being unable to enumerate the USB device.

Everything pointed to a hardware issue.

But in my case, everything worked after resetting the battery (the Acer Swift3 has this option).

I hope my experience helps someone else.

Re: [SOLVED] Bluetooth stopped working, kernel having trouble with its USB

Glad to hear and yes this can often help with weird USB issues, however note that you're responding to a three year old thread https://wiki.archlinux.org/title/Genera … bumping%22 closing this.
