This is because your Launchkey is currently in 'MSD mode' which allows it to appear as a storage device, like a memory stick, so that you can get access to our Easy Start videos.

To take your Launchkey Mini MK3 out of 'MSD mode' and stop any prompts:

1. Disconnect the USB cable from the Launchkey.
2. Hold down the 'Shift' button (1) and connect the USB cable.
3. Press the Yellow pad (2) so it is dim.
4. Press the play button '3' to exit this mode.

The Launchkey will now no longer appear as a mass storage device and will work correctly as a keyboard.
