BUT, USB is a shared resource. Up to 127 devices can be on the bus and
there is no guarantee of timed delivery.
You could identify the device a as a video interface and the USB bus would
allocate specific bandwidth to an interface.
Making a USB based IO EMC2 hardware controller would be the way to go. I
know enough to do the hardware side, but
not enough to do the Ubuntu side.
Then the Parallel port could go away and RIP. It has served it's time VERY
WELL!

The amount of data one could put in a USB microframe, may allow for
more loops per frame so make it easier
