Try examples: https://github.com/robertalks/udev-examples

udev_example2.c can help you get what you want by enumerating all USB
or input (probably the second you want) devices and just getting the
device you want based on attributes.

:~> udevadm info /dev/input/event0|egrep 'SUBSYSTEM|DEVNAME'
E: DEVNAME=/dev/input/event0
E: SUBSYSTEM=input


NOTE: not sure how much of the info you can get, but give it a try.
