	  Userspace access to USB devices is granted by device-nodes exported

	  directly from the usbdev in sysfs. Old versions of the driver

	  core and udev needed additional class devices to export device nodes.



	  These additional devices are difficult to handle in userspace, if

	  information about USB interfaces must be available. One device contains

	  the device node, the other device contains the interface data. Both

	  devices are at the same level in sysfs (siblings) and one can't access

	  the other. The device node created directly by the usbdev is the parent

	  device of the interface and therefore easily accessible from the interface

	  event.



	  This option provides backward compatibility if needed.

	  This option provides backward compatibility for libusb device

	  nodes (lsusb) when usbfs is not used, and the following udev rule

	  doesn't exist:

	    SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
