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. > If the chipsets are undocumented and some proprietary image > compression technique is used, the time to reverse-engineer them can > be quite lengthy. 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).
