kernel 6.5.6 , Ubuntu 22.04. , ASUS MB.
Barrot bluetooth dongle (supposedly fully compatible with CSR)
After desktop startup, the dongle shows in lsusb. But will not function.When I unplug the dongle, then plug in again, the dongle will function.
Why? Any possibility to have the dongle functioning upon startup, with no unplug-plug procedure? Do I need a kernel patch?
Thank you.
