Too bad you didn't mention that hub in your original posting. :-( You can try using different USB cables to attach the hub. Apart from that, I don't know of anything you can do. Well, there is one thing -- but it's awkward and you probably won't want to do it. In 2.6.21 it's possible to force the high-speed hub to run at full-speed. Then the stick would probably work okay, but it would be 40 times slower. As would every other high-speed device plugged into that hub.
