android-open-accessory-bridge implmentaion for Raspberry Pi 2 kitkat

[dcinspe...@gmail.com]

Hello everyone, I am working on a project for work I have a Raspberry pi model 2 model B with KitKat 4.4.2 installed and are in need of some help.

 I have a USB accessory that i wish to use with the raspberry pi as if the pi was an actual phone or tablet (I'm telling you now that it already works with lots of android devices)
the issue I am having is that when I connect my device up to the pi over USB I do not get this notification and so in the end my device does not communicate with its proprietary APP
the bellow picture is what I am looking for when I connect my device, my device worksI have tested it on a few android devices.

Note USB Debugging is enabled on the PI
normaly has to be for this to work
I'm not trying to say that normal USB devices don't work because they do

after some reasearch these are some links I found
