Based on my own experience with USB weirdness with the Pi, I still suspect 
power issues. How are you powering the Pi itself? Using a 1 amp supply yielded 
problems, regardless of the sort of hub I had, which all went away when I 
switched to a 2 amp supply. I'm told the second generation of these boards are 
a bit better on that regard, but I don't have any to test.
