I thought to do the same a lot time ago, but I'm too lazy. I have posted somethink to x50v.it .. anyway..
If I understand well, the problem now is to find/write driver for pxahostusb.. There are some products like toshida g900 or some asus with already built-in these feature.. may be you are already think to use it or to look it .. It's just suggest..
Great job..

Thanks for the suggestions but I've already looked at a number of other PDAs with built-in USB host interfaces. All have used ASICs or 3rd party chips for the interface.
There are 3 host interfaces on the PXA270:
Host port 1 is not connected but IS terminated on the motherboard through two 1.5K resistors to ground. That was my first attempt to connect those to the outside world.
Host port 3 is a single-ended port, also not connected.
Host port 2 uses the USBOTG interface in the client mode. I suspect if someone vould write or obtain an OTG driver for this port, we can get ot working as client and host.
That is where this project sits right now.
