- * usb_serial_driver - describes a usb serial driver

- * @id_table: pointer to a list of usb_device_id structures that define all
- * of the devices this structure can support.
- * @num_interrupt_in: the number of interrupt in endpoints this device will
- * have.
- * @num_interrupt_out: the number of interrupt out endpoints this device will
- * have.

- * @num_bulk_out: the number of bulk out endpoints this device will have.
- * @num_ports: the number of different ports this device will have.
- * @calc_num_ports: pointer to a function to determine how many ports this
- * device has dynamically. It will be called after the probe()
- * callback is called, but before attach()
- * @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.)
