int usb_authorize_device ( struct usb_device * )

Definition at line 2326 of file hub.c.

char* usb_cache_string	(	struct usb_device *	udev,
		int	index
	)

usb_cache_string - read a string descriptor and cache it for later use : the device whose string descriptor is being read : the descriptor index

Returns a pointer to a kmalloc'ed buffer containing the descriptor string, or NULL if the index is 0 or the string could not be read.

int usb_deauthorize_device ( struct usb_device * usb_dev )

usb_deauthorize_device - deauthorize a device (usbcore-internal) : USB device

Move the USB device to a very basic state where interfaces are disabled and the device is in fact unconfigured and unusable.

We share a lock (that we have) with device_del(), so we need to defer its call.

void usb_disable_device	(	struct usb_device *	dev,
		int	skip_ep0
	)

usb_disable_device - Disable all the endpoints for a USB device : the device whose endpoints are being disabled : 0 to disable endpoint 0, 1 to skip it.

Disables all the device's endpoints, potentially including endpoint 0. Deallocates hcd/hardware state for the endpoints (nuking all or most pending urbs) and usbcore state for the interfaces, so that usbcore must usb_set_configuration() before any interfaces could be used.

Definition at line 1138 of file message.c.

void usb_disable_endpoint	(	struct usb_device *	dev,
		unsigned int	epaddr,
		bool	reset_hardware
	)

usb_disable_endpoint – Disable an endpoint by address : the device whose endpoint is being disabled : the endpoint's address. Endpoint number for output, endpoint number + USB_DIR_IN for input : flag to erase any endpoint state stored in the controller hardware

Disables the endpoint for URB submission and nukes all pending URBs. If is set then also deallocates hcd/hardware state for the endpoint.

Definition at line 1056 of file message.c.

void usb_disable_interface	(	struct usb_device *	dev,
		struct usb_interface *	intf,
		bool	reset_hardware
	)

usb_disable_interface – Disable all endpoints for an interface : the device whose interface is being disabled : pointer to the interface descriptor : flag to erase any endpoint state stored in the controller hardware

Disables all the endpoints for the interface's current altsetting.

Definition at line 1115 of file message.c.

void usb_enable_endpoint	(	struct usb_device *	dev,
		struct usb_host_endpoint *	ep,
		bool	reset_ep
	)

usb_enable_endpoint - Enable an endpoint for USB communications : the device whose interface is being enabled : the endpoint : flag to reset the endpoint state

Resets the endpoint state if asked, and sets dev->ep_{in,out} pointers. For control endpoints, both the input and output sides are handled.

void usb_enable_interface	(	struct usb_device *	dev,
		struct usb_interface *	intf,

usb_enable_interface - Enable all the endpoints for an interface : the device whose interface is being enabled : pointer to the interface descriptor : flag to reset the endpoints' state

Enables all the endpoints for the interface's current altsetting.
