Hello Thong, Sure, you can find a work in progress on my personnal fork (branch grpc-usb-1.35.0: https://github.com/fmartinsons/grpc/tree/grpc-usb-1.35.0) .
The code compils and run on my target machine (an embedded linux box with a core i3) but for the moment I'm not able to make my android client talk with the server (I have spurious USB disconnection at server side). I had not the time to go further on my investigations but I'm willing to pursue as soon as possible. Anyway feel free to use this code but be warned it may not work out of the box. I you find bug or improvements on that, I will be very happy to get them in a merge request (or by other means).
