Hey I am using kernel 2.4.14 and the webcam II is not working. It seems
to work fine with Redhats default kernel 2.4.7, but with 2.4.14 stock
kernel it does not work at all. It complains could not open
/dev/video0: no such device. However I do have /dev/video0 to 63. I
have both parallel port and cpia drivers in the kernel and there is a
/proc/cpia/video0 file that says:

Any ideas what is going on here????
