This took a bit more doing than I had expected, apparently my "working" IIfx isn't anymore, so I had to dig out my Q800.
MouseMan, Macintosh Version: Type: Mouse, original handler $01, original address $03, current handler $04. Supports handlers $01, $02, and $04. Does not support handler $03. Register 1 response '4C54303101900103'. The right button doesn't seem to do anything, but the middle button seems to act like the left button, possibly because the appropriate MouseKey driver isn't present.
MouseMan, ADB: Appears as two devices. One is type: Mouse, original handler $01, original address $03, current handler $04. Supports handlers $01, $02, $03, and $04. Register 1 response '9A2022E13C3B8138'. The other is type: Keyboard, original handler $02, original address $02, current handler $02. Supports handlers $02 and $03. Does not support handlers $01 or $04. This second device activates for middle and right mouse clicks. This device doesn't seem to work well as a mouse at the moment, for whatever reason, possibly because it's not the only mouse connected to the system, possibly because the appropriate MouseKey driver isn't present, possibly the rotary encoders are shot.
Intuos 4x5: Type: Wacom Intuos, original handler $6A, original address $04, current handler $6A. Does not support handlers $01, $02, $03, or $04. Register 1 response (with handler $6A selected) '0412319C29680007'. Judging by the LED on the tablet, it recognizes the stylus that I have (specifically, the LED turns from orange to green when the stylus is touched to the surface of the tablet), but it is otherwise unrecognized by the system, possibly because the appropriate driver isn't present.
Unknown Wacom tablet: Type Wacom ArtZ II, original handler $3A, original address $04, current handler $3A. Does not support handlers $01, $02, $03, or $04. Register 1 response (with handler $3A selected) '384850003C000615'. Judging by the LED on the tablet, it doesn't recognize the stylus that I have. Presumably not even having the appropriate driver would help without also finding an appropriate stylus.
