These Android geared devices are not always working with Linux/RetroPie, we got a few topics in the forum for them with issues during connection or - even after connection - not working properly.
Do you have a vendor support page with a manual/instructions on how to make them work with a PC ? Do they have a 'mode switch' between Android/PC connection mode ?

@churchill7 @mahoneyt944 fwiw, it doesn't seem to be a problem on FBNeo, whatever version of the rom i try.
