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. The RTL8761A information is from the following Github issue https://github.com/lwfinger/rtlwifi_new/issues/58 [ 41.468873] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8761 Ziqian SUN (Zamir) (1): Bluetooth: btrtl: Add support for RTL8761B drivers/bluetooth/btrtl.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-)
