Hi Larry, thanks for this. I have a Z3736F tablet so am quite interested in
getting this working, so thank you for your post!

I was able to compile and install the 'troy' branch. However I was not able
to get Bluetooth to work. As others have mentioned I understand this device
connects via SDIO which has been causing problems with detection (neither
lsusb or lspci show the device), however I am on mainline kernel 3.19 which
I think has some fixes for this. I do have (partially?) working WiFi and if
I look in /sys/bus/sdio/devices I do see a single device which I assume is
the combined WiFi / Bluetooth? I haven't confirmed one way or the other yet
so not sure.

mark at mark-tablet:/sys/bus/sdio/devices$ ls -al

If there is anything else you could suggest to test I would be more than
happy to attempt.


I could not get branch 'kernel' to make, as per details below. I am on
mainline kernel 3.19 which may the reason but I don't know for sure.
