So anyone has any idea how to force Fedora to work with BT?
Ubuntu does not have any problems with this BT dongle, it works like a charm. Problems occurs on Fedora 29, 30, 31 and 32. Please help.

Bump. What the heck, no one has any idea?
By this silence you are trying to tell me that Fedora sucks and Ubuntu Server is better than Fedora? As I said BT dongle works like a charm in Ubuntu Server 20.04.

Looks like it might be a kernel issue,
