A bump is not nearly as well received as more info to help with debugging.

I'll list off some things to explain what I'd if I were in your pit at the next event.

Boot the robot and connect to the DS computer using the USB cable. Launch the DS and DB. On the DB choose USB HW. Make sure the DS has comms with the robot.

I'd expect the camera indicator on the DB to turn green and the usage numbers to be fluctuating. I'd expect some LED on the camera to light up and probably stay on.

If you don't have a display, but seem to have data coming from the robot to the computer, I'd check the license on that laptop by going to the NI License manager and looking at both the Vision Acquisition and Vision Development Modules. Open the twists and click on each element under these. If any say that they are not activated or need something, I'd focus on that. If you have difficulties getting the license activated, feel free to call the support number during their hours.

I might also open the diagram of the DB, go to the vision loop, and dig into the code a bit. The code within WPILib doesn't always have lots of comments, and it doesn't always have debugging turned on. So again, this may be better to do while on the phone with support.

By the way, it may also be useful to connect your camera directly to your laptop and verify that the camera still works. Robots sometimes snack on cords, connectors sometimes get broken, etc.
