It depends on the model of Motorola phone. On my phone for example plugging it in to the USB cable will do nothing at all, but once I download the proper driver, the usb cable will communicate with the phone and I can charge it.

Most other brands do not need a driver.

If you want technical reason as to why (this uses the Razor as an example, but it applies to many Motorola phones, see this page
