587 | @param This A pointer to the EFI_USB_HC_PROTOCOL instance.\r | |
588 | @param DeviceAddress Represents the address of the target device on the USB,\r | |
589 | which is assigned during USB enumeration.\r | |
590 | @param EndPointAddress The combination of an endpoint number and an\r | |
591 | endpoint direction of the target USB device.\r | |
592 | Each endpoint address supports data transfer in\r | |
593 | one direction except the control endpoint\r | |
594 | (whose default endpoint address is 0).\r | |
595 | It is the caller's responsibility to make sure that\r | |
596 | the EndPointAddress represents a bulk endpoint.\r | |
597 | @param MaximumPacketLength Indicates the maximum packet size the target endpoint\r | |
598 | is capable of sending or receiving.\r | |
599 | @param Data A pointer to the buffer of data that will be transmitted\r | |
600 | to USB device or received from USB device.\r | |
601 | @param DataLength When input, indicates the size, in bytes, of the data buffer\r | |
602 | specified by Data. When output, indicates the actually\r | |
603 | transferred data size.\r | |
604 | @param DataToggle A pointer to the data toggle value. On input, it indicates\r | |
605 | the initial data toggle value the bulk transfer should adopt;\r | |
606 | on output, it is updated to indicate the data toggle value\r | |
607 | of the subsequent bulk transfer.\r | |
608 | @param TimeOut Indicates the maximum time, in microseconds, which the\r | |
609 | transfer is allowed to complete.\r | |
610 | TransferResult A pointer to the detailed result information of the\r | |
611 | bulk transfer.\r | |
612 | \r | |
613 | @retval EFI_SUCCESS The bulk transfer was completed successfully.\r | |

615 | @retval EFI_INVALID_PARAMETER Some parameters are invalid.\r | |
616 | @retval EFI_TIMEOUT The bulk transfer failed due to timeout.\r | |
617 | @retval EFI_DEVICE_ERROR The bulk transfer failed due to host controller or device error.\r | |
