My Asus Tufbook A17 (8-core Ryzen 7 CPU) running 64-bit Manjaro has precisely
the same problem.  Same kernel; same lsmod | grep bluetooth output.  5.8.x
works fine.

Could you please tell what kernel version / package solved the problem?
In my case (Fedora 33) even latest kernel update (5.9.12-200.fc33.x86_64)
didn't solve the problem.

Finally I figured out where the problem was.
In my case I needed a file /etc/modprobe.d/btusb.conf with the following
content:

options btusb reset=0

This solved the problem for me.
I wonder why this file became suddenly so important (before I never needed it
with the same dongle).
