I don't know. Not sure what would go in that file, either. I can test that
later. I did just try it in the system I'm using now, which is running
udev, and it gets a new number. I see that the number is now up to 36, so
that must increment every time I add/remove a usb thumb drive, scanner,
and maybe any other usb device. On this machine, the scanner is on
005/036, and there's nothing between that and 005/001. I believe that I've
plugged and removed a thumb drive around 30 times since my last reboot.

Edit: or maybe by some other logic. I just plugged in a flash drive, and
it's on 002/048
