On 3 different laptops, and also with my old mpvi pro, i always get an "interface not found" message when i try to flash a vehicle.

When i unplug the usb and plug it back in, it will flash and scan once without issue, but then i have to unplug/reinsert the cable every time. In the scanner, i usually have to rescan for supported parameters as well.

This is with current drivers. Both mpvi pro and mpvi2. 4 different laptops. At least 10 different usb cables on the mpvi pro and 3 different usb cables on the mpvi 2.

What would cause this on so many different combos of hardware? Does anybody have this issue? It's not extremely detrimental, just very annoying.
