Connecting your device to USB accessories
You can use a USB host adapter to connect your device to USB accessories such as a mass storage device or a mouse. If the USB device has a micro USB connector, a USB host adapter is not necessary. USB host adapters are sold separately. Sony does not guarantee that all USB accessories are supported by your device.
This device has a capless USB port. If your device gets exposed to water, ensure that the USB port is completely dry before inserting a USB cable.
