One thing that I think is very important is that the current USB code has
no documentation and its quite difficult to understand at first sight.

Any replacement should have better documentation before it is considered,
is my opinion :)

Also, there is a comment in usbdi(9) to the effect that the OpenUSBDI
specification looks different now. If new, does this code look like the
newer spec?  That could be some kind of improvement..
