/**
* struct usb_driver - identifies USB interface driver to usbcore
* @name: The driver name should be unique among USB drivers,
and should normally be the same as the module name.
* @probe: Called to see if the driver is willing to manage a particular
interface on a device. If it is, probe returns zero and uses
usb_set_intfdata() to associate driver-specific data with the
interface. It may also use usb_set_interface() to specify the
appropriate altsetting. If unwilling to manage the interface,
return -ENODEV, if genuine IO errors occured, an appropriate
negative errno value.
