Bug Description
With bluez 5.33 on Nexus 4 with silo 43 installed.
* Pair and connect a HID device (mouse or keyboard)
-> pairing/connect works
* Use them for a bit
* Power HID device off
* Power HID device on again
* Start using the HID device
-> It doesn't reconnect automatically and also manually connection doesn't seem to work.
With krillin an rc-proposed image 122 (ubuntu 20150914, device 20150821-736d127) this doesn't happen and the keyboard reconnects reliable back to the phone when enabled.

This seems to come down to problems in the kernel part of the bluetooth stack. The linkkeys created during pairing doesn't get stored and taken as temporary which prevents a reconnection. Further investigation is needed.
