Bus 001 Device 010: ID 17ef:6009 Lenovo ThinkPad Keyboard with TrackPoint

[ jonny@thinkpad-t410 ~ ]$ udevadm info -a -p $(udevadm info -q path -n /dev/bus/usb/001/010 )

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.
