It turns out to be a rebadging of a supported device. Simple addition to
detection table is enough to make it work. It's broken down in 3 patches:
1. Adding to usbdevs
2. Running Makefile -f Makefile.usbdevs
3. Adding to detection tables
Since patch 2 is large and is pure regeneration I don't send it here but
can do so upon request.
