Hi,

I bought a Bluetooth 5.3 USB device from Realtek, RTL808.

When I plug it on my Proxmox server, I have the following messages :

Code:
[  334.951149] usb 1-1: new full-speed USB device number 4 using xhci_hcd
[  335.100138] usb 1-1: New USB device found, idVendor=0bda, idProduct=a729, bcdDevice= 2.00

[  335.103281] Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8761bu_fw.bin not found

I found some links talking about this error, but even after following those advices and rebooting the server, I still have the issue. I also installed bluetooth and bluez packages, pve-headers-6.2.16-19-pve, latest pve-firmware, but I can't solve this issue.

Can someone help ? Thanks !
 
Did you install the firmware-realtek package? Note that the package is in the non-free-firmware repository.
