Can you use the mini-stick or POV hat as buttons/keys?
Yes.
How is simplicity itself. For the POV hat, simply uncheck the box which says "Use as POV" in CH Control Manager. Now press the hat in one direction and look at the first drop-down box. It'll say "None." Change that to CM Device 1 and locate the highest button currently in use. For most of you, that'll be 16. So, press the POV hat forward towards the mini-stick and assign that to CM Device 1, Button 17. Wash-rinse-repeat for the other seven directions on the POV hat. Push the hat down, assign to CH Device 1 Button 18, and keep on going. AH and every other game will recognize the POV hat as four (or eight) more buttons and not as a hat switch. Using this trick I set my 8-way hat as four more buttons and use 'em as elevator and aileron trim controls.
For the mini-stick, push it left and uncheck "DX Mode." Now push it up and uncheck the box again. Make sure the "Up/Down" option is selected, change the "Steps" to 1. Now put your mouse cursor in the "Inc Key" field and hit a key. Say you want to assign the left-right mini-stick action to aileron trim. Usually those keys are J and L, so in the "Inc Key" field hit J, and use L in the Dec Key. Done. Save it, download it to your throttle, and you're off.
