24 to this node at `/dev/block/<type>/<parent device>/<basename uevent DEVPATH>`,
25 `/dev/block/<type>/<parent device>/by-name/<uevent PARTNAME>`, and `/dev/block/by-name/<uevent
27 2. USB devices are created as `/dev/<uevent DEVNAME>` if `DEVNAME` was specified for the uevent,
28 otherwise as `/dev/bus/usb/<bus_id>/<device_id>` where `bus_id` is `uevent MINOR / 128 + 1` and
29 `device_id` is `uevent MINOR % 128 + 1`.
30 3. All other devices are created as `/dev/<basename uevent DEVPATH>`
50 `subsystem_name` is used to match uevent `SUBSYSTEM` value
