Send data from android to pc by USB (C#)

How I can sending data from Android to USB by USB connection? I need send data from unity android app to pc app on windows forms or unity app. Its will look like unity remote, sending data by only usb cable, without external devices for example adruino etc.

Sockets is what you need, forget sql, it’s not fit for the job.

I have no idea what are you talking about. unity remote is an app which connect your mobile phone and the unity editor. so you can simulate phone touch and behaviour in the editor.
