Excellent, thanks. That's exactly what I was looking for. I'll get the entry
removed this weekend.

Um. I'm not good with udev rules, unfortunately. Plus, the syntax has
changed a few times, and the 2 rules I'd managed to write no longer work. I
recommend these two sites:

http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html
http://www.reactivated.net/writing_udev_rules.html

Or, if nothing else, send an email to this udev/hotplug list (you can find
it at the first URL above).

I'll CC ya'll on the patch to remove the entry.

Thanks for taking an interest in having your device work on Linux. We always
welcome vendors who are willing to work with the Linux community.
