TP-Link UB500 Bluetooth USB adapter not working properly

[gwendydd]

I have just bought a Tp-link bluetooth 5.0 usb adapter (UB500). According to this website https://usb-ids.gowdy.us/read/UD/2357/0604 the chip is Realtek RTL8761B.
It works just fine on Windows 10, but I'm having problems on Ubuntu.

I'm running Ubuntu 21.10 with the 5.14.14-051414-generic kernel

The adapter seems to be correctly installed and properly working, however scanning does not pick up any bluetooth device. I've tried two headsets (that I know are properly working) and my phone, with no success. When performing a scan on my phone, the computer doesn't show up, even if I've set it to visible.

(I'm sorry if the information is not complete, but ubuntu-bug is not working for me)

This change was made by a bot.

The device should be added to btusb.c

 /* Tp-Link UB500 */
{ USB_DEVICE(0x2357, 0x0604), .driver_info = BTUSB_REALTEK },

The chip is supported, but the ID is not there.

Solved with kernel 5.15.4-arch1-1

Can we expect this in 20.04.04?

Could you please let us know when this fix will be available for Ubuntu Ubuntu 20.04.3 LTS?
