Hi,

The descriptors you sent look OK.

Can you run webcamd from gdb and trace all the parameters and code path 
taken inside the function named usb_setup_endpoint which triggers after 
you run pwcview ?

gdb
file webcamd
run -d ugenX.Y
CTRL+C
break usb_setup_endpoint
continue
next
next
next
....


Let's skip Freebsd-current and freebsd-x11 in the CC'ing of this thread 
to reduce the amount of cross-posting? Or which list do you prefer?
