The "rest" of the info in there should be split out of usb.ids and
probably just imported into the .c code directly, as it's not anything
that changes very often, if at all.  I can move that directly into
usbutils without an issue.

I agree with Kay, the options it provides should just be moved into the
.c code itself.  I added it years ago when someone sent it to me as it
provided some options that the existing .c code didn't handle.  Other
than color support, I don't think that is true anymore, but I'll look
closer at it to make sure.
