[SOLVED]USB Bluetooth 5.0 tp-link UB500

I bought a new Bluetooth 5.0 adapter, tp-link UB500

Bus 001 Device 006: ID 2357:0604 TP-Link TP-Link UB500 Adapter

I downloaded/unzip Windows drivers and found information on the drivers to install:

Copyright(c) 2017,  RealTeK Technology Inc. All Right Reserved.
 *   
 *	Realtek Bluetooth 8761B Driver package Release Note

RTBlueR_Windows_1015.1016.1016.0427.2021_2.00.263_F027_B
Version:		
1015.1016.1016.210427

I installed from AUR rtl8761usb-dkms and I checked for /lib/firmware/rtl_bt/rtl8761b_fw.bin and /lib/firmware/rtl8761b_config.bin

yay bluez 
yay bluez utils
systemctl start bluetooth.service

After installing sudo dmesg | grep bluetooth gives no message and the switch to enable bluetooth in Gnome Settings is stuck.

Did you get this to work? I have the same device (TP-Link UB500) and while it seems to be detected by the OS, it does not appear to be able to scan for devices. My machine's internal bluetooth device works OK.

It looks like that adapter will be supported in a new kernel version: https://www.spinics.net/lists/linux-blu … 94476.html
For the dkms driver, a similar entry would have to be added to "btusb_table" in usb/bluetooth_usb_driver/rtk_bt.c

I found this: https://kernel.googlesource.com/pub/scm … 52186632e4

It would be interesting to test this: https://aur.archlinux.org/packages/linux-mainline/

Solved with kernel 5.15.4-arch1-1

Solved as in, the driver is included in 5.15.4-arch1-1 by default?

EDIT: the answer is yes, I can see the relevant change in git.
