Hm, this is strange. I have not seen this constellation as long as you are connecting the computer and ECU directly via a standard USB cable.
If you are using a special cable you might have to install a driver.
I would recommend to unplug everything, then checking the windows device manager and see if you might have some missing drivers for your computer in general.
Hmm, ok. Maybe I'll try an other cable and maybe even an other computer. I am borrowing this PC as I am a Mac guy. My limited windows knowledge is based on a few generations back, this current OS is hard to figure out.
