Re: [Spca50x-devs] vimicro trouble, feel like helping out?

Hi Groente,

    Some time ago I wrote a paper describing how to
find the sensor of a webcam. Take a look at:

http://zc0302.sourceforge.net/docs/HOWTO-Finding_the_sensor_type.html

    Your bridge is a zc030x because of the USB id:
0ac8

Hope this helps. Ulisses
