USB Receiver (Base) Doesn't Work

If you think that your keypads are not communicating (not working/voting), please refer to this article.

First of all, always start with going to the Get Feedback/EZ-VOTE toolbar and check Base Settings. If you see the receiver listed in the window (with a COM number and BaseID assigned to it) - that's a good thing. Close the window and try running your slide deck in Presentation Mode again.

Otherwise, if your suspicion is that the base (receiver) is the one with a problem, here are the main reasons why that might be the case.
