+ * @probe: pointer to the driver's probe function.
+ *	This will be called when the device is inserted into the system,
+ *	but before the device has been fully initialized by the usb_serial
+ *	subsystem.  Use this function to download any firmware to the device,
+ *	or any other early initialization that might be needed.
+ *	Return 0 to continue on with the initialization sequence.  Anything
+ *	else will abort it.
+ * @attach: pointer to the driver's attach function.
+ *	This will be called when the struct usb_serial structure is fully set
+ *	set up.  Do any local initialization of the device, or any private
+ *	memory structure allocation at this point in time.
+ * @shutdown: pointer to the driver's shutdown function.  This will be
+ *	called when the device is removed from the system.
+ *
+ * This structure is defines a USB Serial driver.  It provides all of
+ * the information that the USB serial core code needs.  If the function
+ * pointers are defined, then the USB serial core code will call them when
+ * the corresponding tty port functions are called.  If they are not
+ * called, the generic serial function will be used instead.
+ *
+ * The driver.owner field should be set to the module owner of this driver.
+ * The driver.name field should be set to the name of this driver (remember
+ * it will show up in sysfs, so it needs to be short and to the point.
+ * Useing the module name is a good idea.)
