Classes
struct	usb_hardware_func
	Description of controller-specific data and functions. More...
struct	usbhc_func
	pointers to kernel API functions that are called from *HCI-drivers More...
struct	usb_controller
	Controller descriptor. This structure represents the common (controller-independent) part of a controller for the USB code. The corresponding controller-dependent part *hci_controller is located immediately before usb_controller. More...
struct	usb_pipe
	Pipe descriptor. An USB pipe is described by two structures, for hardware and for software. This is the software part. The hardware part is defined in a driver of the corresponding controller. The hardware part is located immediately before usb_pipe, both are allocated at once by controller-specific code (it knows the total length, which depends on the hardware part). More...
struct	usb_static_ep
	This structure describes the static head of every list of pipes. More...
struct	usb_gtd
	This structure represents one transfer descriptor ('g' stands for "general" as opposed to isochronous usb_itd). Note that one transfer can have several descriptors: a control transfer has three stages. Additionally, every controller has a limit on transfer length with one descriptor (packet size for UHCI, 1K for OHCI, 4K for EHCI), large transfers must be split into individual packets according to that limit. More...
struct	usb_interface_data
	Interface-specific data. Several interfaces of one device can operate independently, each is controlled by some driver and is identified by some driver-specific data passed as is to the driver. More...
struct	usb_device_data
	Device-specific data. More...
