If I buy the 3 device license, will I be able to use 2 devices on the Steam Link simultaneously?

Like the title says, I want to use an X55 Rhino with my Steam Link but I need the ability to use more than 1 USB device. If I buy a license will I be able to use more than 1 USB device on the Steam Link or would I just be wasting money? Thanks for any information.

Sure, you can use up to 3 devices simultaneously, or unlimited for the unlimited license
