The iPAQ Pocket PC h5500 Series ships with a USB cradle. This cradle connects to a computer via a Universal Serial Bus (USB) connection. A USB cable is also provided to directly connect the device to a USB port on a PC. USB is a peripheral bus standard that allows users to attach peripheral devices to a computer on the fly, without having to reboot or reconfigure the system. USB devices are automatically configured as soon as they are physically attached.
note:
USB Does Not Provide Power - Neither the USB cradle nor the direct USB cable provides power to the iPAQ. Power must still be supplied from the internal battery or through the AC adapter that is included with the unit.
