Re: Joystick Connection Issues
  1. Keep your laptop plugged in at all times while on the field.
  2. Change your USB device settings to disallow Windows from cutting power to the USB ports to save power when the laptop is not plugged in.
  3. Test your controllers every match after you've connected to the field (look for the Setup tab blue when pushing a controller button).
  4. Don't let your laptop go to sleep or hibernate. The USB power gets re-negotiated when Windows wakes up.
Warning: power hungry controllers may brown out during competition. Basic controllers (no fancy lights) connected directly to the laptop USB ports (not hubs) are safest. When the driver station laptop battery gets low it begins to cut power to USB ports starting with the ports with the highest power drain. Usually, that means starting with ports connected to bigger drain USB hubs that have several devices hanging off them.
