ugen is no option for multi interface devices, e.g. scanner/printer
combo.
ugen is a device level driver and once you have an interface level
driver like ulpt attached you can only share the device with other
interface level drivers.
Well uscanner currently is a device level driver as well, but that's
more a bug and is changeable.

If uscanner attaches to a scanner, why do you want it via libusb?
Where is the problem with uscanner vs. ugen/libusb?
Do we need any uscanner enhancements?
