From: Zamir SUN <sztsian@gmail.com> This patch adds support for the RTL8761B USB Bluetooth dongle. When I got the RTL8761B dongle, I see it is actually recognised as RTL8761A in my system (5.5.15-200.fc31.x86_64 on Fedora). And the userspace cannot detect bluetooth devices in such situation.

After applying this patch along with the firmware I am able to use this dongle. Note, I don't have RTL8761A device, so I would appreciate if someone can help test in case this patch breaks RTL8761A.
