My recently replaced MPVI was working fine, but today after I successfully flashed a tune I started the scanner and got the Interface Not Found message. I verified the USB ports are working and I connected to another vehicle and got the same thing.
I can pull the info from the unit and the power light comes on when the obd cable is connected or the USB cable is connected.
I do not see the device in Device Manager when connected, not sure if that's expected.
Windows 10 on a Dell laptop.
What's next? I'm kind of in a bad spot now.
