I'm getting the same error messages but also silent failures.
Having Bluetooth scan enabled it will detect devices correctly for
30-120s, then it will keep discovering fewer and fewer devices to a
point at which it can not see any bluetooth devices anymore. Then, after
some more time it might start reporting "Bluetooth: hci0
*somethingsomething* command failed"
The only workaround is to:
modprobe -r btusb
modprobe btusb
I'm forced to do it every minute or so when it becomes flaky.
