Not an ideal solution but there is a way to reset at the field without a computer. To set up a 2 pos switch for 2D/off or 3D/off you have to have the travel set in the tx to zero (neutral) in one direction and typically max travel in the direction of the desired mode. So, to do a reset with the tx just program the neutral direction back to max travel so you have 2D/3D. Do the reset. Then put the travel back to neutral.
Fortunately this doesn't need to be done often, especially after a plane is set up. This method is a bit awkward but a lot easier than lugging a laptop to the field and fishing around for the USB connection.
