Anker keyboard doesn't send key events to krillin

[Brendan Donegan]

I have an Anker BT keyboard which seems to work fine on the Nexus 4 with Android, but when I use it with Krillin and Ubuntu it doesn't seem to receive keypresses. In fact I have used a hack boot.img to get it to even connect. The exact model is : http://www.amazon.co.uk/Compact-Wireless-Bluetooth-Keyboard-Rechargeable/dp/B00PIMRCFG/ref=sr_1_2?ie=UTF8&qid=1441209196&sr=8-2&keywords=anker+bluetooth+keyboard

This comes down to a critical problem in the krillin kernel where two HID drivers conflict at startup time and the BT never gets loaded which ends up with the userland side never being able to create a BT HID input device.

Kernel fix for this is submitted and waiting for review.

After some more analysis the BT HID stack in the krillin kernel seems to be horrible broken. We will not going to fix but replace this pretty soon with a complete new bluetooth stack which will be based on an recent upstream kernel (4.2). We have to wait until this is done until we have a solution for this bug.

However just conencting a keyboard should be possible once the mentioned kernel fix is merged and published, it will just not allow you to enter anything.

Fixes landed with latest device tarball for krillin/vegetahd.
