Does the 4155 have a USB host port? Normally, the USB on a PPC device is
USB function, and works with Microsoft ActiveSync. It wouldn't be able to
communicate with a HID device. Also, the USB function port is the slave in
these scenarios, it isn't going to be used to get data from another device.

If it has USB OTG or USB host, it would be possible for the Ipaq to be in
control of communications. But it might be more work than you are hoping
for...
