Comment 10 for bug 1591167

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.
