I'll bet it's a power issue, not a driver one. Try hooking it up
through a powered hub: if it works, that means it needs power for the
additional electronics that the tablet can't provide. If it doesn't
work, it's probably a driver issue. I know that my N800 can't power
USB memory drives, but works fine with my keyboards. Although it's
amazing to me that it actually can power the receiver for my wireless
keyboard. I would have thought that that would take at least as much
power as a memory drive, but apparently not.
