USB Modem fun and games

[Brian Somers]

I think you need usbd_enable=YES in /etc/rc.conf so that usbd starts up
and notices the arrival of usb devices.

If it doesn't recognise your modem, I think it tells you the device name
that can be used in usbd.conf, but I think it should ``just work'' once
usbd is enabled.
