Making some progress. Figured out roughly how this hotplug data is gathered and edited the C and header files accordingly. Now it recognizes the camera:

Aug 12 00:55:21 zero kernel: drivers/usb/media/stv680.c: [stv680_probe:1399] STV(i): STV0680 camera found.
Aug 12 00:55:21 zero kernel: drivers/usb/media/stv680.c: [stv680_probe:1437] STV(i): registered new video device: video0

However, it won't let me read from it, and the perms seem to me like they should allow it:

open("/dev/video0", O_RDONLY|O_LARGEFILE) = -1 EPERM (Operation not permitted)
write(2, "head: ", 6head: ) = 6
write(2, "/dev/video0", 11/dev/video0) = 11
write(2, ": Operation not permitted", 25: Operation not permitted) = 25
write(2, "\n", 1) = 1
exit_group(1) = ?
jcomeau@zero:~/www/www/blog$ ls -l /dev/video0
crw-rw-rw- 2 root sys 81, 0 Mar 9 2003 /dev/video0

Here's the patch so far:
