얘는 udev management tool 이라고 하니

이걸 uinput이 아니라 udev라고 하나 따로 파야하나..?

$ udevadm info -a -n /dev/input/event24

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
