But I think we already have enough information to test a setup like this.
Of course, sofware will be required :rolling:

You'll KILL the device if you use 5V on the interface chip:exc: :exc:
EDIT: No, you won't kill the device - looking at the specs, pin 1 is used for transient suppression of the 5V line, so yes, you CAN connect it to 5V (But no higher).
Look carefully at the schematics - you'll find that the line labelled USBH0_VBUS is NOT connected. This is VERY important. You need to remember that you will be interfacing 3V and 5V signals.
Let me do some research on the interface chips before you start publishing schematics that someone might use and kill their PDA. I know you want to get this figured-out quickly - but you don't want to kill anything either.
Also, have a look at this great reference:
