What do you mean? We are talking about connecting an android phone to a Linux PC, right? What do you expect to do? I can send file, clipboard, use phone to remote controle the PC (slide show, media playing), I can use a virtual keyboard on android that get input from the PC keyboard,I can have android notification on PC and the other way arround, I can even use the phone SIM to send SMS from the PC and other stuff I almost never use.
I don't know if I can use the phone camera as a webcam for the PC or to scan QR code, would be neat.
Not sure whatelse you want to do with fingerprint and sensor.
