7 title: Generic USB Device

13   Usually, we only use device tree for hard wired USB device.
15   http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
17   Four types of device-tree nodes are defined: "host-controller nodes"
18   representing USB host controllers, "device nodes" representing USB devices,
19   "interface nodes" representing USB interfaces and "combined nodes"
20   representing simple USB devices.
26   A "hub node" is a combined node or an interface node that represents a USB
31     pattern: "^usb[0-9a-f]{1,4},[0-9a-f]{1,4}$"
33       "usbVID,PID", where VID is the vendor id and PID the product id.
41     description: the number of the USB hub port or the USB host-controller
42       port to which this device is attached. The range is 1-255.
45   "#address-cells":
50   "#size-cells":
54   "^interface@[0-9a-f]{1,2}(,[0-9a-f]{1,2})$":
56     description: USB interface nodes.
58       representation of an interface-node unit address for configuration 1.
62         pattern: "^usbif[0-9a-f]{1,4},[0-9a-f]{1,4}.config[0-9a-f]{1,2}.[0-9a-f]{1,2}$"
64           "usbifVID,PID.configCN.IN", where VID is the vendor id, PID is
65           the product id, CN is the configuration value and IN is the interface
