[Cambridge Silicon Radio] Bluetooth fails to reconnect after waking
from sleep on 20.10

Status in linux package in Ubuntu:

Bug description:
After upgrading to 20.10, my mouse either takes an extraordinarily
long time to reconnect (2+m), or it never reconnects until I unplug
and replug my usb bluetooth dongle. It was slow to reconnect on 20.04
(10-30s), but it seems pretty much broken on 20.10.
