Query: Works Fine but I Hate It! Most Typical Keyboards Won't Work!

It works as long as you have a keyboard that it wants to work with! I have stacks of all sorts of USB keyboards but the only one that works is one Kensington keyboard. All the others including stock Dell and HP keyboards won't function. Who manufactures a device that can't work with most stock keyboards?
