I have a Logitech vertical mouse. I can move the mouse and click. The scroll wheel does not register on macOS, neither in Safari, nor Finder, or other.
On Linux, it works like a charm. Therein, I can also use
xev, and see any mouse panning, click, or scroll, trivially.
How can I dump mouse wheel events, at different layers of the stack? Over USB, since it's HID, could just use Wireshark and USB capture… if it's implemented on OS X. But further up?
