Actually, your case is quite strange, I thought the PCI bus was always 
probed before USB, so the PCI card should always get the first device.

Actually, I see in /lib/udev/rules.d a file 60-persistent-v4l.rules, so it 
seems there is already something to write persistent rules for video 
devices.
If I understand it correctly, it should generate symlinks in /dev/v4l/by-id 
and /dev/v4l/by-path, so maybe you should use those links which are supposed 
to always point to the same device regardless of its actual numbering.
