I hear questions like this asked a lot: "can I connect my <GPS / printer / scanner / etc> to my pocket pc?". Let me explain some technical background about USB and the ARM chips the PPC is based on.
USB is centered around this notion of master-slave and device tree. There is the root hub which is the root device, then there may be some hubs in between, and ultimately there are the leaves (USB slaves). The master needs to be able to provide up to 0.5A of current to power the slave device.
The Intel PXA chip, as well as its predecessor StrongArm chips, is a System-On-Chip. It has a CPU and a bunch of other stuff, including the USB circuitry, on the chip; and that USB circuitry is just USB slave. Therefore, the PPC will most definitely NOT drive any kind of USB periphery: it just lacks the fundamental "master" circuitry to do it. So to answer your GPS question, the only way to have GPS is via BT -- either a BT GPS, or your existing USB one through an adapter.
