Causes hardware resource information (such as IRQ, I/O ports, I/O memory addresses) to be also listed, under each device that has reserved those resources.
-u
Displays the same information as with -r but sorts by resource type rather than by device, allowing to review the set of system resources by usage and available resources. I.e., it lists all the IRQ consumers together.
-v
Display all devices in the driver tree, not just those that are attached or busy. Without this flag, only those devices that have attached are reported.
