please RTFM (read the fine
manual) :-} Especially about the HID class (this will help you to set up the other mouse buttons according to your needs) and the requirement to install MUIWheelPatch under AmigaOS (not required for MorphOS).
PS: Pressing the HELP key in the Trident GUI and/or the class prefs GUI will normally load up the specific page of the manual.
