MCX8000 can not connect under win7

I had a problem durig installation firmware version 1.0.5. The system can not recognise the hardver. The windows didn’t find a proper driver, despit of i have a latest version. Somebody was a similar problem? Can anybody help for me?

try using a different usb port and try deleting the drivers windows already had started. and give it some time when it connects. that usually works for me when I am trying to plug in a new controller
