The example gives Consumer:Volume_Down and Consumer:Volume_Up, but when I look in the mentioned /usr/share/misc/usb_hid_usages under Consumer, they are listed as Volume_Decrement and Volume_Increment.
I confirm that this is incorrect ("awk '/^[0-9]+/{print} /Volume/{print}' /usr/share/misc/usb_hid_usages" shows that Consumer only has "Volume", "Volume Increment", and "Volume Decrement").
