/**

* 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.
