562d2849 | 2015 | Routine Description:\r |
4d1fe68e | 2016 | \r |
2017 | Submits an asynchronous interrupt transfer to an\r | |
562d2849 | 2018 | interrupt endpoint of a USB device.\r |
4d1fe68e | 2019 | Translator parameter doesn't exist in UEFI2.0 spec, but it will be updated\r |
ac842714 | 2020 | in the following specification version.\r |
4d1fe68e | 2021 | \r |
562d2849 | 2022 | Arguments:\r |
4d1fe68e | 2023 | \r |
562d2849 | 2024 | This - A pointer to the EFI_USB2_HC_PROTOCOL instance.\r |
2025 | DeviceAddress - Represents the address of the target device on the USB,\r | |
4d1fe68e | 2026 | which is assigned during USB enumeration.\r |
2027 | EndPointAddress - The combination of an endpoint number and an endpoint\r | |
2028 | direction of the target USB device. Each endpoint address\r | |
2029 | supports data transfer in one direction except the\r | |
2030 | control endpoint (whose default endpoint address is 0).\r | |
2031 | It is the caller's responsibility to make sure that\r | |
2032 | the EndPointAddress represents an interrupt endpoint.\r | |
562d2849 | 2033 | DeviceSpeed - Indicates device speed.\r |
2034 | MaximumPacketLength - Indicates the maximum packet size the target endpoint\r | |
4d1fe68e | 2035 | is capable of sending or receiving.\r |
562d2849 | 2036 | IsNewTransfer - If TRUE, an asynchronous interrupt pipe is built between\r |
4d1fe68e | 2037 | the host and the target interrupt endpoint.\r |
2038 | If FALSE, the specified asynchronous interrupt pipe\r | |
2039 | is canceled.\r | |
2040 | DataToggle - A pointer to the data toggle value. On input, it is valid\r | |
2041 | when IsNewTransfer is TRUE, and it indicates the initial\r | |
2042 | data toggle value the asynchronous interrupt transfer\r | |
2043 | should adopt.\r | |
2044 | On output, it is valid when IsNewTransfer is FALSE,\r | |
2045 | and it is updated to indicate the data toggle value of\r | |
2046 | the subsequent asynchronous interrupt transfer.\r | |
2047 | PollingInterval - Indicates the interval, in milliseconds, that the\r | |
2048 | asynchronous interrupt transfer is polled.\r | |
2049 | This parameter is required when IsNewTransfer is TRUE.\r | |
2050 | DataLength - Indicates the length of data to be received at the\r | |
2051 | rate specified by PollingInterval from the target\r | |
2052 | asynchronous interrupt endpoint. This parameter\r | |
2053 | is only required when IsNewTransfer is TRUE.\r | |
562d2849 | 2054 | Translator - A pointr to the transaction translator data.\r |
4d1fe68e | 2055 | CallBackFunction - The Callback function.This function is called at the\r |
2056 | rate specified by PollingInterval.This parameter is\r | |
2057 | only required when IsNewTransfer is TRUE.\r | |
562d2849 | 2058 | Context - The context that is passed to the CallBackFunction.\r |
2059 | - This is an optional parameter and may be NULL.\r | |
4d1fe68e | 2060 | \r |
562d2849 | 2061 | Returns:\r |
4d1fe68e | 2062 | \r |
2063 | EFI_SUCCESS\r | |
2064 | The asynchronous interrupt transfer request has been successfully\r | |
562d2849 | 2065 | submitted or canceled.\r |

562d2849 | 2067 | Some parameters are invalid.\r |
4d1fe68e | 2068 | EFI_OUT_OF_RESOURCES\r |
2069 | The request could not be completed due to a lack of resources.\r | |

4d1fe68e | 2326 | \r |
2327 | Submits synchronous interrupt transfer to an interrupt endpoint\r | |
2328 | of a USB device.\r | |
2329 | Translator parameter doesn't exist in UEFI2.0 spec, but it will be updated\r | |
ac842714 | 2330 | in the following specification version.\r |
4d1fe68e | 2331 | \r |
562d2849 | 2332 | Arguments:\r |
4d1fe68e | 2333 | \r |
562d2849 | 2334 | This - A pointer to the EFI_USB2_HC_PROTOCOL instance.\r |
4d1fe68e | 2335 | DeviceAddress - Represents the address of the target device on the USB,\r |
562d2849 | 2336 | which is assigned during USB enumeration.\r |
4d1fe68e | 2337 | EndPointAddress - The combination of an endpoint number and an endpoint\r |
2338 | direction of the target USB device. Each endpoint\r | |
2339 | address supports data transfer in one direction\r | |
2340 | except the control endpoint (whose default\r | |
562d2849 | 2341 | endpoint address is 0). It is the caller's responsibility\r |
4d1fe68e | 2342 | to make sure that the EndPointAddress represents\r |
2343 | an interrupt endpoint.\r | |
562d2849 | 2344 | DeviceSpeed - Indicates device speed.\r |
4d1fe68e | 2345 | MaximumPacketLength - Indicates the maximum packet size the target endpoint\r |
562d2849 | 2346 | is capable of sending or receiving.\r |
4d1fe68e | 2347 | Data - A pointer to the buffer of data that will be transmitted\r |
562d2849 | 2348 | to USB device or received from USB device.\r |
4d1fe68e | 2349 | DataLength - On input, the size, in bytes, of the data buffer specified\r |
562d2849 | 2350 | by Data. On output, the number of bytes transferred.\r |
2351 | DataToggle - A pointer to the data toggle value. On input, it indicates\r | |
4d1fe68e | 2352 | the initial data toggle value the synchronous interrupt\r |
2353 | transfer should adopt;\r | |
2354 | on output, it is updated to indicate the data toggle value\r | |
2355 | of the subsequent synchronous interrupt transfer.\r | |
2356 | TimeOut - Indicates the maximum time, in microseconds, which the\r | |
562d2849 | 2357 | transfer is allowed to complete.\r |
2358 | Translator - A pointr to the transaction translator data.\r | |
4d1fe68e | 2359 | TransferResult - A pointer to the detailed result information from\r |
2360 | the synchronous interrupt transfer.\r | |
562d2849 | 2361 | \r |

562d2849 | 2370 | Some parameters are invalid.\r |
4d1fe68e | 2371 | EFI_TIMEOUT\r |
562d2849 | 2372 | The synchronous interrupt transfer failed due to timeout.\r |
4d1fe68e | 2373 | EFI_DEVICE_ERROR\r |
2374 | The synchronous interrupt transfer failed due to host controller\r | |
2375 | or device error. Caller should check TranferResult for detailed\r | |
2376 | error information.\r | |
