Trust Vista Remote Keyboard Will A Keyboard With An Attached Mouse Work With Another Mouse Attached?

Will a keyboard with an attached mouse work with another mouse attached? - trust vista remote keyboard

I have a very expensive laser mouse that I want to keep, but I have a keyboard with cable. I want a wireless keyboard, but connected in groups with a mouse or mouse fall. The one I are interested in purchasing a trackball is the keyboard. I wonder if my old USB mouse still works with the new wireless keyboard with trackball attachments without turning off the hardware and others.

Buy a link here is where I want to:
