Connect your device to a USB device
To connect your BlackBerry device to a USB device, you must have a micro USB on-the-go to USB 2.0 adapter.
You can access and save files on an external storage drive by using the File Manager app. You can also connect to external
USB devices, such as a keyboard, mouse, or gamepad.
Insert the micro USB on-the-go to USB 2.0 adapter into the USB port on your device.
Connect the adapter to an external USB device.
