Vision Sensor seems to not detect anything at all.

So recently I did some research (including posting another topic about vision sensor) on the vision sensor, and I decided to use the example in Vex V5.

The thing is, it clearly detects the red bucket. But on the brain, it says “No Red Object”.
Plus, the light of the vision sensor isn’t on either way.
Am I doing something wrong?

Need to see your code.
(also, disconnect the vision sensor USB when running code on the brain)
