Do you have any antivirus running that may be wanting to disinfect/control access to usb drives?
You say no devices except mouse and keyboard but there is a very long devices list in that log?
Maybe starting windows in safe mode and also tweeting with all av disabled will give clues?
And have you correctly selected what type of connection from th phones drop down connect as... Menu.
My wife has a Samsung s7 and that will default to connecting for charging, not frmfile transfer, each time unless manually changed.
