Any switch we have works because we don't require voltage.
We think this is where we are at.

Now that you know why you aren't getting anything from the encoder, it is time to move upstream, and figure out why you aren't getting any power on the DIO pins.
WHat color is your power LED? Red? If so you probably have a short from 5V to GND
Start by unplugging everything, and visually inspect all of the slots to ensure no debris is present. Verify the Power LED is Green, and measure the voltage on the DIO +5V pins again.
If you have power now, start looking for your short. Take each connector, one at a time, and verify there is no continuity between pins 2 and 3 on the connector. If there is no continuity, plug it back in and verify that you still have 5V power. If there is continuity, or when you plug it in you lose power, then inspect the cable, and device to find and fix the short.
Edit- Apparently I was slow replying.

My only concern with this approach is that if the issue is something like a 5V short from debris in the controller, then that debris could move, causing different, potentially worse symptoms.
