- This resets all of the USB bus logic, including the USB host
- controller hardware and all the devices attached on the USB bus.
- EFI_USB_HC_RESET_HOST_CONTROLLER
- If this bit is set, the USB host controller hardware will be reset.
- No reset signal will be sent to the USB bus.
- EFI_USB_HC_RESET_GLOBAL_WITH_DEBUG
- If this bit is set, a global reset signal will be sent to the USB bus.
- This resets all of the USB bus logic, including the USB host
- controller hardware and all the devices attached on the USB bus.
- If this is an EHCI controller and the debug port has configured, then
- this is will still reset the host controller.

- EFI_INVALID_PARAMETER
- Attributes is not valid.
- EFI_UNSUPPOURTED
- The type of reset specified by Attributes is not currently supported by

- EFI_ACCESS_DENIED
- Reset operation is rejected due to the debug port being configured and

- DeviceAddress - Represents the address of the target device on the USB,
- which is assigned during USB enumeration.
- EndPointAddress - The combination of an endpoint number and an
- endpoint direction of the target USB device.
- Each endpoint address supports data transfer in
- one direction except the control endpoint
- (whose default endpoint address is 0).

- Data - Array of pointers to the buffers of data that will be transmitted
- to USB device or received from USB device.
- DataLength - When input, indicates the size, in bytes, of the data buffer
- specified by Data. When output, indicates the actually
- transferred data size.
- DataToggle - A pointer to the data toggle value. On input, it indicates
- the initial data toggle value the bulk transfer should adopt;
- on output, it is updated to indicate the data toggle value
- of the subsequent bulk transfer.
- Translator - A pointr to the transaction translator data.
- TimeOut - Indicates the maximum time, in microseconds, which the
- transfer is allowed to complete.
- TransferResult - A pointer to the detailed result information of the
- bulk transfer.
-
- Returns:
-
- EFI_SUCCESS
- The bulk transfer was completed successfully.
- EFI_OUT_OF_RESOURCES
- The bulk transfer could not be submitted due to lack of resource.
- EFI_INVALID_PARAMETER
- Some parameters are invalid.
- EFI_TIMEOUT
- The bulk transfer failed due to timeout.
- EFI_DEVICE_ERROR
- The bulk transfer failed due to host controller or device error.
- Caller should check TranferResult for detailed error information.
