I'm getting this problem with my Palm LifeDrive, and with my Arduino microcontroller board.
Neither device is even detected when connected with USB. A /dev isn't assigned. The problem goes away when I sudo modprobe -r ehci_hcd. I've documented some of my experiences with this bug on this thread: http://ubuntuforums.org/showthread.php?t=760518 Please fix!
