I have had my HPT mpvi pro interface for a few years now and have used it without issue. I have recently run into an issue where the interface will not connect to my vehicle or any other vehicle i have tuned with it anymore.
I am using it on my 09 ctsv that I have been tuning without an issue for over a year. The cables and interface are connected properly. The green light will illuminate when the interface is connected to the vehicles obdII port. When I plug the USB cable in, the computer will not recognize it anymore. There is no tone when the USB cable goes in or out.
When attempt to send a file or log, a message will pop up stating
"The interface was not found. Verify it is connected properly and that the vehicles diagnostic port has power."
The USB port does work properly with any other USB cable in the same port.
Any help will be appreciated.
