The user can request usage() output with -h or --help or something

This should probably be implemented by passing a FILE pointer to usage().
usbconfig doesn't actually have a -h option, usage() output is just a default
fall-through.
Ugh. It documents -h in its man page. Its code doesn't even use getopt().
It uses a home made parser that accepts almost any random character as an
equivalent for -h.
