Title:
Add support for EDUP Bluetooth 5.1 USB
Status in linux package in Ubuntu:
Confirmed
Bug description:

send one, and just followed the instructions in a thread I found
online!
---------------
The EDUP Bluetooth dongle uses the Realtek RTL8761B chipset, and seems
to work fine with the existing RTL8761B driver after manually
patching the kernel following this guide:
