I have this same problem with hardy.

[  443.450761] usb 2-1: new high speed USB device using ehci_hcd and address 14

[  444.900206] usb 2-1: device not accepting address 17, error -71

its just this acomdata external hdd that does not work for me. All my other usb sticks work properly. 
i can modprobe -r ehci_hcd and it mounts as usb 1.1

However if i plug it in before boot up it mounts properly as usb 2.0

I tested with a jaunty live cd and it mounts as usb 1.1 unless plugged
in before boot. And again all my other devices work properly.

let me know if there's any other logs i can post to help.
