Reuben,

If you're willing, then open up the device and see what the chips within
are.  You believe it's em28xx based, but there may well be additional
devices in there for audio and video.

Once you've found out what's inside it will be easier to get it working.
It may be as simple as getting the driver to recognise the USB Vendor ID
or it may require much more work.

Regards,

Gareth
