There's some support in libusb for accessing non-ugen(4) devices, specifically control transfers and synchronous reads. But if this code is to do some necessary initialization for a particular printer that can be matched by IDs, adding support right in the ulpt(4) driver would probably be better, there's already some framework for matching things by ID for printers which need firmware to be uploaded, so you could possibly hook into this.
