Bluetooth device not loading anymore on the host

[vacar84]

Hello

I used to use the BT built-in antenna with one of the VM I have on the host and never had any issue. All of a sudden the BT hardware disappeared from the list of the USB device I could use in a VM and cannot get it back. It looks like it's not loading properly in the host anymore. Any suggestion how I can at least try to understand what's going on?

Thanks a lot for your help

hi,

does it show up in lsusb? do you see any message/error in dmesg -w output when you plug the device in/out?

does it work on different device?

what is your pveversion -v output?

This the lsusb output:

none of them is the BT antenna

I cannot unplug/plug it on a different device as it's the built in BT module which I believe it's embedded in the Wifi card or something like this. I do actually have a portable usb BT antenna which does work on other linux device, but that doesn't work on the pve too.. Perhaps I could use this one (even better) but I cannot manage to install the firmware correctly. It's this one

dmesg -w could you be a little more specific? That commands returns a huge output, perhaps dmesg -w | grep usb but this one doesn't output anything helpful too it seems..

this the PVE versions ouput:

sorry! i thought it was an external adapter so my suggestion was running dmesg -w and waiting, then plugging/unplugging the device should show you some output if it's being detected.

none of them is the BT antenna

hmm. do you see anything in lsmod | grep bluetooth ?

also you could check if booting an older kernel version makes any difference

sure no problem!

So this is the lsmod | grep bluetooth ouput:


In order to boot an older kernel, to be honest I have no idea how to do that, but I'll find it out and test it.

Thanks for your help in the meantime !
