of the complexity of a single USB physical device, the representation of the device in sysfs is also very complex. Both the physical USB device (represented by struct usb_device) and a single USB interface (represented by struct usb_interface) appear in sysfs as a single device because both structures contain a struct device structure. The following is the direc
