Well, you can always use the USB port in the express card, which is
one of the smartest things the working group added to the spec.  That
enabled manufacturers to start selling expresscards immediately, and
was better for laptop user who started collecting lots of usb dongles
for various applications.  Now there's a specific spot in the computer
to hold your USB device, and if you really need speed then a single
lane of PCIx is available
