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.
