I have a similar set of toys working nicely on 2.6.2 (Hmm, I should probably
update). Did you remember to enable hotplug support (CONFIG_HOTPLUG=y)? If
so what do your logs say. When I plug in a jumpdrive I get this in dmesg:
hub 3-0:1.0: new USB device on port 3, assigned address 2

BTW, once you get everything working you should look into using udev. It
really helps manage a large collection of usb dongles because you can have
it generate unique symlinks in /dev (ie /dev/jukebox, /dev/camera) instead
of trying to keep track of what is on /dev/sda1 this time.
