Thus after the host controller hardware negotiates a slow connection,
then perhaps a udev rule might detect (see "lsusb -v"):
bcdUSB < 2.00
bInterfaceClass = 8 Mass Storage
bInterfaceProtocol = 80 Bulk (Zip)
and raise a warning for me. Or perhaps I should consider working with
the dbus, or (depending on the desktop environment) enhancing the auto-
mounting apparatus. I really dislike USB storage at only 1.5MB/s.
