HI @fadia,

This keyboard looks to have a more complicated communication between the usb dongle and the pc. I believe there is software associated with this keyboard. I do not believe this keyboard is using a standard ps/2 communication which is what the other keyboards your mentioned use. My only other suggestion would be to use a usb powered hub in case the usb dongle is drawing to much current for the usb host on the Nexys 4.
