The only difference between them when walking the usb tree is the 
Serial, Product, and urbnum which is randomly assigned.

udevadm info -a -p $(udevadm info -q path -n /dev/video1)
Here's the one for a 4903. I wonder if you see see any difference 
between it and the 4900 you have.

   looking at parent device
