Comment 26 for bug 54273

I've just run into this bug.

Since a couple of days I've been trying to recover data from my notebook HD and for that purpose I got an empty usb box but ubuntu would not see it.

Browsing around I eventually ended up here http://ubuntuforums.org/showpost.php?p=1082418&postcount=8

modprobe -r ehci_hcd worked and I am now backing up.
