--- Comment #146 from Babak (b.razmjoo@protonmail.com) ---

Hi everyone, I have bought a dongle just like Andres's in
https://bugzilla.kernel.org/show_bug.cgi?id=60824#c81 and my system has
problems activating it. This is my system:

Linux localhost.localdomain 5.7.9-200.fc32.x86_64 #1 SMP Fri Jul 17 16:23:37
UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

These are result of running commands recommended here:

$ hciconfig -a
