Host Controller Endpoints Sample Clauses

Host Controller Endpoints. Endpoint Descriptors are the structures which appear in lists that the Host Controller processes. Above that Host Controller Driver and USBD submit transfer requests to “endpoints”. An endpoint structure is maintained until the connection to the endpoint is close, while an Endpoint Descriptor is maintained only while there is scheduled transfers to the endpoint. USBD coordinates the creation and deletion of endpoint structures and provides memory within each endpoint structure for Host Controller Driver to maintain is state. In this example, the HCD- specific area of an endpoint structure would be defined as: typedef struct _HCD_ENDPOINT { UCHAR Type; UCHAR ListIndex; UCHAR Reserved[2]; PHCD_DEVICE_DATA DeviceData; HC_ENDPOINT_CONTROL Control; PHCD_ENDPOINT_DESCRIPTOR HcdED; PHCD_TRANSFER_DESCRIPTOR HcdHeadP; PHCD_TRANSFER_DESCRIPTOR HcdTailP; ULONG Rate; ULONG Bandwidth; ULONG MaxPacket; } HCD_ENDPOINT, *PHCD_ENDPOINT; Table 5-4: HCD_ENDPOINT Field Description Type Isochronous, Interrupt, Control, Bulk ListIndex Index into device data EdList. This is the identifier of which list ED for this endpoint are to be inserted. DeviceData Pointer to corresponding device data for the HC to which the endpoint is connected. Control PID, direction, etc. HcdED Current endpoint descriptor which is scheduled. HcdHeadP This is a virtual pointer to the first TD on this endpoint’s queue HcdTailP This is a virtual pointer to the last TD on this endpoint’s queue, unless it is in the process of being filled in this is a dummy structure. Rate This is the requested polling rate for an interrupt endpoint, the actual rate used is indicated by ListIndex. Bandwidth For isochronous or interrupt endpoints, this value represents the amount of bandwidth which is required for the endpoint when it’s opened. For control or bulk endpoints, this value represents the maximum packet size to be transferred to or from the endpoint in any one packet. MaxPacket Maximum packet size for this endpoint.
