hello everyone. I currently use one controller to operate our robot, but the hotshot challenge says two drivers and two controllers should be used. If anyone could help me with using multiple logitech controllers it would be very much appreciated.

The 2009 FTC rules say two drivers/joysticks canbe used; not should. It is up to teams to determine whether they need one or two joysticks.
If you want to use two joysticks, you just need to address the correct joystick in your code (joy1 vs joy2) and make sure you have the dual joystick checkbox on the joystick control debug window checked.
In the FCS, it will prompt you to press the correct buttons on each of the joysticks to register them.
