The USB device itself comes up as :

    Bus 001 Device 011: ID 0547:8031 Anchor Chips, Inc

The sensor is a Micron MT9T001P12STC and I have the data sheet for it.

I've asked the manufacturer for source code to the windows driver
and docs/source/whatever for the USB interface.

I happen to know that the sensor/camera (via the windows driver) can
provide raw bayer data which is what I'm after (our application is
machine vision and bayer works best).

Cheers,
Erik
