Hi,
Why you still trying to make more problems in this car if you know there is something wrong with your USB connection?
As I remember, you did many times MSX8X ISN reading, now you are facing the same problem in CAS and DME (interrupting in the process)
Please, SOLVE the usb problem before you try anything else. If you find that Autohex II WVCI has a problem, contact support and ask them to check it.
