FWIW, a couple of Windows updates ago, my bench TIU suddenly stopped properly loading sound and chain files with the USB port. I switched to the serial port and all was well. I'm not sure what happened, but it was a Windows 10 change that broke the USB in my case.
FYI, the USB connector on the TIU is the same type that appears on a vast range of USB products, it's the industry standard. The most common USB cable on the planet is the USB A to B cable, it's used in a LOT more than printers. I have disk drives, scanners, UPS boxes, etc. that all use the same connection.
