/* struct usb_device_driver - identifies USB device 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
* device. If it is, probe returns zero and uses dev_set_drvdata()
* to associate driver-specific data with the device. If unwilling
* to manage the device, return a negative errno value.
* @disconnect: Called when the device is no longer accessible, usually
* because it has been (or is being) disconnected or the driver's
* module is being unloaded.
* @suspend: Called when the device is going to be suspended by the system.
* @resume: Called when the device is being resumed by the system.
* @drvwrap: Driver-model core structure wrapper.
* @supports_autosuspend: if set to 0, the USB core will not allow autosuspend
* for devices bound to this driver.
*
* USB drivers must provide all the fields listed above except drvwrap.
