When you connect to internet ,software automaticly connects to ross tech server, updates list of cloned serial numbers and sends command to Atmel inside interface to erase first few bytes of 93c46 eprom( attached to ft232bl) and erase few lines in Atmel.. so it doesn;t "kill" the interface... you must reprogram Atmel and 93c46 , and it will work... First symptom of "killed" interface is that windows doesn't recognize it and won;t accept drivers... another symptop is LED blinking RED colur only..
Chinese tred to fix that with some IC inside that "fixes" that ,but ofcourse, they failed... Their ,so called " never locks " interfaces work terrible and very unstable... With regular ,good hardware , you can do what you want to inteface...disconect in middle of working, unplug, plug, start the car in middle of measurnig blocks and it will always "come back" and reconnect itself in few sec. ...never freezes
