tried compiling the source code using different configurations in music-players.h but to no avail.
I'm not sure if i understand how to add support for this device or how to debug it.
Any help or pointers is appreciated

Found that the MTP application had been disabled under android > settings > applications > MTP.
MTP works with version 1.20
