I don't believe this is possible. Sure you can enable the USB ports, but because it is a DirecTivo, it will still look for the phone. All your guide information comes down over the satellite with DTV, and the phone line is used for PPV. My buddy and I enabled his USB ports last year, but when you would turn on the DTiVo it would still complain about the phone.
