It is just a simple udev rule. In /etc/udev/rules.d you can create a
new file named what ever you want ending with .rules. Then you put a
line like this in there:
BUS=="usb", KERNEL=="js*", NAME="hiddev%n"
I use somewhat similar to rename a usb device. The udev rules document
A couple of points so you don't have to reboot so often. If you run
"udevcontrol reload rules" It will read in the rules and do what they
say. You might have to pull out the device and plug it back in.
