I have the u727 also, but I haven't tested it with conecting it to the tablet yet, namely because I don't have a USB cable that can change gender. I know the u727 advertises linux ready, but I couldn't get to work in Ubuntu the other day when we had a lightning storm that briefly knocked out the cable and subsequently, the cable modem. I'd say it was entirly possible, just figuring out how is the question.
