I've had this problem on 10.2, too (with iPod), but now that i've tried
again on 10.3 alpha 1, it seems to be gone.
However, here's what i've been told to try by kernel people: try to
unload ehci-hcd kernel module (run 'rmmod ehci-hcd' as root) and see if
that helps. This will disable USB 2.0, and leave you with 1.1 (there
were reports of such problems when using 2.0)
