STRUCT 
USB_SG_REQUES(9) 				  Host-Side Data Types and Macro				   STRUCT USB_SG_REQUES(9)

NAME

       struct_usb_sg_request - support for scatter/gather I/O

SYNOPSIS

       struct usb_sg_request {
	 int status;
	 size_t bytes;
       };

MEMBERS

       status
	   zero indicates success, else negative errno

       bytes
	   counts bytes transferred.

DESCRIPTION

       These requests are initialized using usb_sg_init, and then are used as request handles passed to usb_sg_wait or usb_sg_cancel. Most members
       of the request object aren't for driver access.

       The status and bytecount values are valid only after usb_sg_wait returns. If the status is zero, then the bytecount matches the total from
       the request.

       After an error completion, drivers may need to clear a halt condition on the endpoint.

STRUCT 
USB_DEVICE_DR(9) 				  Host-Side Data Types and Macro				   STRUCT USB_DEVICE_DR(9)

NAME

       struct_usb_device_driver - identifies USB device driver to usbcore

SYNOPSIS

       struct usb_device_driver {
	 const char * name;
	 int (* probe) (struct usb_device *udev);
	 void (* disconnect) (struct usb_device *udev);
	 int (* suspend) (struct usb_device *udev, pm_message_t message);
	 int (* resume) (struct usb_device *udev, pm_message_t message);
	 struct usbdrv_wrap drvwrap;
	 unsigned int supports_autosuspend:1;
       };

MEMBERS

       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.

DESCRIPTION

       USB drivers must provide all the fields listed above except drvwrap.
