More info needed to provide a useful answer.

my program is working perfectly but when i am in my FRC Drivers Station and i go Diagnostics i see that my Joysticks aren't blinking when i move them; they only blink when i press the joystick buttons that's it

That is the expected behavior.

In Windows, you can go to "Set Up USB Game Controllers" to see if they are working.

We are also experiencing our joysticks randomly drop out. This was happening a lot last year during our regional. We switched to a different joystick this year, an xbox usb controller without led lights. It seemed to be working fine all weekend in NYC then in the semifinals it happened again (of course perfect timing It was strange because this time only one joystick dropped out (the xbox one) the other joystick, a logitech gamepad, remained functional. Anyone know why this might be happening? And what can we do to avoid this at our next regional.

As stated above, that is normal.

Have you actually tried testing them with the robot enabled?

My guess is you'll be happily surprised with the results.

Isn't F1 also the ENABLE hotkey?

We'll try that but.... Has anyone else experienced this and if so how can we fix it so the joysticks never drop out!!

Are the joysticks plugged into a USB hub or directly into the USB ports on the driver station? We had a similar issue twice in the past and both times it was related to the USB hub that we were using. Once it was that the devices were not getting sufficient power from the single USB port to support them both. The second time it was the USB hub that had its own signal continuity issues; these problems disappeared when that hub was replaced. In both cases the signals to the joysticks were dropping out sometimes momentarily and sometimes persistently. We have since eliminated the hub from our driver station (since we have only 2 USB devices and no longer need the external e-stop button) and have had no issues like that since.

Some laptops disable or limit the power draw from USB ports on battery power, or when battery is below a certain level. You may be able to disable this behavior. I've also seen weird results when using some USB hubs.

Make sure you always check the joysticks before the beginning of the match.
