USB Middle mouse on button settings.
On the old magic mice you used to be able set a function on the middle button on USB mice. The problem is with a standard USB mouse, this isn't available on Macs anywhere I can find.
I've found older threads where people seem to go "Thats up to the manufacturer to support it". And thats nonsensical, as the Middle mouse button is a USB-IF HID standard, likely going back as far as v1.1 of the spec, (For the fellow software devs in the room, its bit 3 on byte 1 on the standard 3 byte USB response packet), so part of the USB HIB device class standards is this is something the OS itself "knows" how to support. This is why things like mice dont need to come with drivers.
The problem is, I cant find anywhere to configure this. You can configure the Left and Right buttons. Is there a command line way to assign this, or any third party apps that can configure this?
