PC keep throwing my android device out so i cant test game on unity remote.

Hello. I have windows 10, android phone, unity remote 5 on it and Unity 5.5 (free personal version). I am working on a project for mobile devices. I came to that point when i have to customize and optimize settings for acceleration and speeds. I want to test game via usb and unity remote, but its not working. I enabled usb debugging on phone, set to android project and enabled it for any android device. my problem is when i plug in phone via usb port, my pc detects it but after 1 second phone gets disconnected then again pc detects it and again after few second it gets disconneted this is repeating all the time. Connecting other USBs is normal without troubles. I tried to connect my phone to another pc (there is no Unity on it) and it works without problems. I think that problem is in Unity free version because i factory reset both devices, try other usb cable, update all usb drivers.... i dont know what else to do. Can anyone give me good advice or help me solve the problem? Thanks and Good regards.
