title: How to change Android usb connect mode to charge only?
body: <p>I've seen HTC android devices have connect mode selection when connected to PC via usb line, while mine always pops up a <code>USB massive storage device</code> dialog with a button <code>turn on massive storage</code>, which is boring, because sometimes my line could be loose, and <code>off/on</code> randomly, so the pop up always show up suddenly and intrudes my input when I'm doing something else. Is the a way to fix this?</p>
