But please allow me to point out that I have doubts that HID or input is at fault, because when sniffing on the USB bus with usbmon, I do *not* see any information transported when pressing the middle button. Therefore, I would suspect it is rather the base USB driver that somehow needs a quirk to access the mouse properly.
