Hi,

Based on this information your driver is located in:

media_tree/drivers/media/usb/gspca/zc3xx.c

Maybe you can diff the "media_tree/drivers/media/usb/gspca" directory 
between the working version of webcamd and the non-working. I don't see 
how any non-linux kernel sources should cause this regression right now.

Also, make sure you specify a fps setting which is supported:

pwcview -s vga -f 5

For example. Still doesn't work?

--HPS
