Jim Wilson, embedded MVP (Jim, where's your blog site URL?) - has posted an excellent tutorial on how to get Phidgets working with the ICOP eBox 2300, here's a link to the tutorial.
Here's what the tutorial (including images) covers:
How to create a CE 6.0 OS Design
How to include external drivers in your OS Design, not originally included with the BSP.
How to include and configure the CE software components (CoreCon) needed to make a connection for application debugging.
How to make an application automatically load when CE starts up.
How to use the Phidgets API to write a simple application to control a servo while obtaining readings from an A/D interface connected to an IR ranging sensor.
How to install your final OS Design on the eBox 2300 for automatic booting.
Obviously the tutorial can easily be modified to also work with other devices.
