This isn't right...

usb-storage should only be creating a new device node if it does not find a
record with a matching GUID that is not currently in use.  This suggests
one of the following:

(a) usb-storage gets a connect for the EHCI before it gets the disconnect
from the OHCI (I would consider that a USB core bug).
(b) The device has a varible GUID because it does something stupid like use
it's bus address as a serial number.

I'd love to figure out which it is....
