How do I connect my Cymbal 2 to a computer via USB?

Connect your phone to the computer with a USB cable, and the Connect to PC options menu will open automatically. You can choose from Charge only, Install driver, Media device (MTP) for transferring files on Windows or Mac, or Camera (PTP) for transferring photos if MTP is not supported. To disconnect, simply unplug the USB cable when finished. (Page 40-41)
