https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #195 from Jack (ostroffjh@xxxxxxxxxxxxxxxxxxxxx) --- Yahoo. Upgraded to kernel 5.13.10. dmesg is similar to earlier kernel (Comment 192) but the device is now recognized, and I can pair it with my Sony BT headphones. Not really sure what changed that made the difference.

I do find it interesting that it says V5.0 on the device, but btmon shows Bluetooth 4.0, although for a cheap dongle from eBay, I'm not surprised. -- You may reply to this email to add a comment.
