If it is really an Amiga mouse, then it does not need any driver. You just plug it into the mouse port and it works as if the original Amiga mouse was plugged in. The middle button of course has no function normally because no software makes use of it.
Those drivers on Aminet are for serial PC mice which plug into the serial port.
Do not plug an Amiga mouse into the serial port and do not plug a serial mouse into the Amiga mouse port. Both might destroy the mouse and the port.
