Hi, passing UB500 bluetooth in a fedora kde vm. it seems to work but hang at some point, sometime not connect/ not work after vm reboot.

TP-Link UB500 2357:0604,RTL8761BU, fw 0xdfc6d922

I looked and found there is issue with this bluetooth and it's firmware with kernal patch available

is this fix available on proxmox 9 latest? i am on Proxmox 8 so i wonder if upgrading could fix this? if specific pveversion 7.0.14-25 will work?

Thanks.
 
It's unclear whether upgrading to Proxmox VE 9 would resolve the issue, as it may also be related to the guest OS kernel or Bluetooth driver.

Could you share the kernel version (uname -r) running inside the Fedora VM and any Bluetooth-related logs from when the issue occurs?

i am on 7.0.14-25-pve now. not a vm issue as i faced similar issue with ubuntu gnome. it is indeed tplink firmware that is hanging at some point. i have tried finding the logs and not see anything unsual, except the devices stop working(not disconnected) randomly.
