If I understand correctly, you want to use the Nexys 4 or 3 USB port with PS2 signals.
You can do this as is. If you go to the section of the reference manual for the Nexys 4 to the USB HID section you can see that the microcontroller emulates old style PS2 signals.
The Auxiliary Function microcontroller hides the USB HID protocol from the FPGA and emulates an old-style PS/2 bus. The microcontroller behaves just like a PS/2 keyboard or mouse would. This means new designs can re-use existing PS/2 IP cores.
