Ubuntu 18.10
Bluez Version: 5.50-0ubuntu1
After changing batteries in my bluetooth mouse, it is connected but
doesn't work (no movement or clicking). Fix is to re-pair it.

Title:
[Dell DW1560 / BCM20702A1] kobject_add_internal failed for hci0:11
with --EEXIST, don't try to register things with the same name in the
same directory
Status in linux package in Ubuntu:
Confirmed
Bug description:
kobject_add_internal_failed for hci0:11 with --EEXIST, don't try to
register things with the same name in the same directory
This issue is about kernel - it shouldn't rely on state of unrealiable
propertary drivers. Sometimes rmmod all bluetooth modules helps,
sometimes restart is just faster.
