What is the USB Port for?

I have an R22, and was curious as to what the USB ports on them where for??

The only real use for them is to run a fan for cooling, or charge your cell phone.

Not sure about the R22, but the USB port on the HR21-HR24 is used for the external OTA tuner (AM21).

That's the one on the back, I was talking about the one on the front. Looking at the original post, he said ports, so I think we have it covered!
