Powering your USB Hub at Competition

[csshakka]

If this solves the problems we were having at the Traverse City competition, this will be very, very appreciated. Out of all of the matches played, we were able to play 1 full match completely, and 2 others for a very brief period. After that it appeared that there was no comm. The field manager helped out a ton, and told us that each time a few seconds into teleop, comm was lost. We had tried multiple wireless adapters and locations for it to sit with no avail. We also have a bunch of joysticks connected to a usb hub only connect to one port on the classmate.

After seeing this thread and mentioning it to one of our mentors, he suggested getting a powered usb hub that connects to a normal ac/dc line, but whip up a device to connect it to something like a 9V battery to power it while up at the match stations. Would this provide more available power for the usb hub then getting a y connector and plugging it into both ports on the classmate?
