@Nikhil:
the bug didn't appear in lucid (for me) and i recognized it for the first time in natty (but i don't know whether the bug appears in maverick too)
@torstenaf:
sounds interesting. Can you check your dmesg-log for entries like:
[ 968.188033] usb 1-8: new high speed USB device using ehci_hcd and address 6
and after reappearing (same bus):
[ 1005.992037] usb 2-8: new full speed USB device using ohci_hcd and address 4
If it's a driver issue there is definitively something wrong with the communication between ohci_hcd and ehci_hcd.
