Template:FAQ/Questions/goliath verdex USB host

Why do the Goliath expansion boards only work with verdex motherboards ?

 * The GPS and GPRS control functions are both connected to the USB host function of the verdex motherboards.


 * As basix and connex motherboards do not offer USB host, neither of these motherboards work with Goliath expansion boards - even though they might fit onto the 60-pin connector.


 * There is a USB hub controller on the Goliath board, which means that all the USB devices will be usable simultaneously by the gumstix.


 * The Goliath boards give verdex motherboards full-speed USB access to the Siemens MC75 GPRS/EDGE module, the u-blox NEO-4S GPS module, and one external USB device.
