Sorry, I mistyped - it is the SZ variant with color LCD and 66MHz CPU that
is being considered.

The USB interface is not a USB 'HOST' but rather a USB endpoint. I.e, a
SZ328 system with propper software support becomes a USB device, rather
than a host (or, to use simpler terms, a controller). As such, this port
will not be able to accept other USB devices directly, although there
appears to be a way to do this using some sort of a USB bridge device,
something which is commonly used in USB to USB networking cables, for
instance. Specs on this are very difficult to find. I have only seen it
referred to in a completely unrelated document (for a Cirrus - Crystal MP3
player chip), where this approach is used to connect USB mass memory
devices.

This is what I am trying to find out at the moment. There is a bit of a
mechanical problem with it as it uses a BGA case, which requires special
soldering equipment, but I think this could be circumvented with a
different approach to PCB design.
