USB 10 Key multi -TV remote

Good afternoon, I am working on a remote that will be hardwired to multiple TVs. It will have presets as well as some other basic functions to control the TVs.

Here is my hang up. I want to use a USB 10 key with my Arduino Due. I have tried multiple 10 keys but none of them work. When I use a standard Keyboard all is well. Any ideas?

Can anyone help me at all?

What is one of these?

If it is a keyboard with a USB port on it you need a USB host shield to make this work.
