Yes, that code need to be ported to usb2 (you dont want to use it with old usb),
dont ask me how to do that, please. Ask Hans. Probably it needs libusb 2.0.

Also note that usb2(USB4BSD) is compatible with linux usb, so it should make
all this type of things trivial.

Oh my god, it is pain to have more than one usb stack at same time.
