1924 | Data - Array of pointers to the buffers of data that will be transmitted \r | |
1925 | to USB device or received from USB device. \r | |
1926 | DataLength - When input, indicates the size, in bytes, of the data buffer\r | |
1927 | specified by Data. When output, indicates the actually \r | |
1928 | transferred data size. \r | |
1929 | DataToggle - A pointer to the data toggle value. On input, it indicates \r | |

2163 | Routine Description:\r | |
2164 | \r | |
2165 | Submits an asynchronous interrupt transfer to an \r | |
2166 | interrupt endpoint of a USB device.\r | |
ac842714 | 2167 | Translator parameter doesn't exist in UEFI2.0 spec, but it will be updated \r |
2168 | in the following specification version.\r | |
2169 | \r | |
562d2849 | 2170 | Arguments:\r |
2171 | \r | |
2172 | This - A pointer to the EFI_USB2_HC_PROTOCOL instance.\r | |
2173 | DeviceAddress - Represents the address of the target device on the USB,\r | |
2174 | which is assigned during USB enumeration. \r | |
2175 | EndPointAddress - The combination of an endpoint number and an endpoint \r | |
2176 | direction of the target USB device. Each endpoint address \r | |
2177 | supports data transfer in one direction except the \r | |
2178 | control endpoint (whose default endpoint address is 0). \r | |
2179 | It is the caller's responsibility to make sure that \r | |
2180 | the EndPointAddress represents an interrupt endpoint. \r | |
2181 | DeviceSpeed - Indicates device speed.\r | |
2182 | MaximumPacketLength - Indicates the maximum packet size the target endpoint\r | |
2183 | is capable of sending or receiving. \r | |
2184 | IsNewTransfer - If TRUE, an asynchronous interrupt pipe is built between\r | |
2185 | the host and the target interrupt endpoint. \r | |
2186 | If FALSE, the specified asynchronous interrupt pipe \r | |
2187 | is canceled. \r | |
2188 | DataToggle - A pointer to the data toggle value. On input, it is valid \r | |
2189 | when IsNewTransfer is TRUE, and it indicates the initial \r | |
2190 | data toggle value the asynchronous interrupt transfer \r | |
2191 | should adopt. \r | |
2192 | On output, it is valid when IsNewTransfer is FALSE, \r | |
2193 | and it is updated to indicate the data toggle value of \r | |
2194 | the subsequent asynchronous interrupt transfer. \r | |
2195 | PollingInterval - Indicates the interval, in milliseconds, that the \r | |
2196 | asynchronous interrupt transfer is polled. \r | |
2197 | This parameter is required when IsNewTransfer is TRUE. \r | |
2198 | DataLength - Indicates the length of data to be received at the \r | |
2199 | rate specified by PollingInterval from the target \r | |
2200 | asynchronous interrupt endpoint. This parameter \r | |
2201 | is only required when IsNewTransfer is TRUE. \r | |
2202 | Translator - A pointr to the transaction translator data.\r | |
2203 | CallBackFunction - The Callback function.This function is called at the \r | |
2204 | rate specified by PollingInterval.This parameter is \r | |
2205 | only required when IsNewTransfer is TRUE. \r | |
2206 | Context - The context that is passed to the CallBackFunction.\r | |
2207 | - This is an optional parameter and may be NULL.\r | |
2208 | \r | |
2209 | Returns:\r | |
2210 | \r | |
2211 | EFI_SUCCESS \r | |
2212 | The asynchronous interrupt transfer request has been successfully \r | |
2213 | submitted or canceled.\r | |
2214 | EFI_INVALID_PARAMETER \r | |
2215 | Some parameters are invalid.\r | |
2216 | EFI_OUT_OF_RESOURCES \r | |
2217 | The request could not be completed due to a lack of resources. \r | |
2218 | EFI_DEVICE_ERROR\r | |
2219 | Can't read register\r | |

2473 | Routine Description:\r | |
2474 | \r | |
2475 | Submits synchronous interrupt transfer to an interrupt endpoint \r | |
ac842714 | 2476 | of a USB device. \r |
2477 | Translator parameter doesn't exist in UEFI2.0 spec, but it will be updated \r | |
2478 | in the following specification version.\r | |
562d2849 | 2479 | \r |
2480 | Arguments:\r | |
2481 | \r | |
2482 | This - A pointer to the EFI_USB2_HC_PROTOCOL instance.\r | |
2483 | DeviceAddress - Represents the address of the target device on the USB, \r | |
2484 | which is assigned during USB enumeration.\r | |
2485 | EndPointAddress - The combination of an endpoint number and an endpoint \r | |
2486 | direction of the target USB device. Each endpoint \r | |
2487 | address supports data transfer in one direction \r | |
2488 | except the control endpoint (whose default \r | |
2489 | endpoint address is 0). It is the caller's responsibility\r | |
2490 | to make sure that the EndPointAddress represents \r | |
2491 | an interrupt endpoint. \r | |
2492 | DeviceSpeed - Indicates device speed.\r | |
2493 | MaximumPacketLength - Indicates the maximum packet size the target endpoint \r | |
2494 | is capable of sending or receiving.\r | |
2495 | Data - A pointer to the buffer of data that will be transmitted \r | |
2496 | to USB device or received from USB device.\r | |
2497 | DataLength - On input, the size, in bytes, of the data buffer specified \r | |
2498 | by Data. On output, the number of bytes transferred.\r | |
2499 | DataToggle - A pointer to the data toggle value. On input, it indicates\r | |
2500 | the initial data toggle value the synchronous interrupt \r | |
2501 | transfer should adopt; \r | |
2502 | on output, it is updated to indicate the data toggle value \r | |
2503 | of the subsequent synchronous interrupt transfer. \r | |
2504 | TimeOut - Indicates the maximum time, in microseconds, which the \r | |
2505 | transfer is allowed to complete.\r | |
2506 | Translator - A pointr to the transaction translator data.\r | |
2507 | TransferResult - A pointer to the detailed result information from \r | |
2508 | the synchronous interrupt transfer. \r | |
2509 | \r | |
2510 | Returns:\r | |
2511 | \r | |
2512 | EFI_SUCCESS \r | |
2513 | The synchronous interrupt transfer was completed successfully.\r | |
2514 | EFI_OUT_OF_RESOURCES \r | |
2515 | The synchronous interrupt transfer could not be submitted due \r | |
2516 | to lack of resource.\r | |
2517 | EFI_INVALID_PARAMETER \r | |
2518 | Some parameters are invalid.\r | |
2519 | EFI_TIMEOUT \r | |
2520 | The synchronous interrupt transfer failed due to timeout.\r | |
2521 | EFI_DEVICE_ERROR \r | |
2522 | The synchronous interrupt transfer failed due to host controller \r | |
2523 | or device error. Caller should check TranferResult for detailed \r | |
2524 | error information. \r | |
