Maybe your question is outdated, but since noone answered yet.

- You can enhance our uhid driver
- You can write your own driver
- You can do raw control transfers via /dev/usb*
- You can also do raw control and pipe trandfers if ugen takes the
  device
- You can use libusb for portable (Linux, ...) device access via ugen
