A reasonable starting point is to learn the overall USB architecture, if you want to implement a USB host stack on the PDA (if this is what you plan to do.) Anyone who thinks about tinkering with the host controller driver should be very familiar with most of the USB specification, and that is one thick and boring document, heavy on hardware. Your PDA also should have a suitable USB hardware (host controller). You need to find out what it is, and to what standard type of HCs it conforms to. After that is done, you need to go through errata of the chipset and find everything about bugs in the silicon. Armed with this knowledge, you take one (suitable) Linux HC driver and compile it for the PDA. Then you run it, and it should work :-) If it doesn't then you just debug it...
