No problem, take your time, just don't forget to let us know when you
get it to work :)

A common problem is that, even when you run newhidups as the "root"
user, it will actually drop root privileges before opening the USB
device. To prevent it from dropping them, you must give it the "-u
root" option (you can get around this by setting up some hotplugging
magic, but you shouldn't bother with that until the "-u root" option
first works).
