Im in the middle of tuning a truck and my cable just went out. I flashed the truck and went to open the scan tool after I was done and it said no interface cable found. My laptop then pops up a message that my usb device has errors and will not work. I have rebooted my laptop and even tried another computer, nothing reconizes my cable anymore. I have this truck to finish and 2 more today and 5 more tomorrow. I have the workshop cable if that matters.
