Callback functions
| PUSB_BUSIFFN_ENUM_LOG_ENTRY This callback function is not supported. The EnumLogEntry routine makes a log entry. |
| PUSB_BUSIFFN_GETUSBDI_VERSION The GetUSBDIVersion routine returns the USB interface version number and the version number of the USB specification that defines the interface, along with information about host controller capabilities. |
| PUSB_BUSIFFN_IS_DEVICE_HIGH_SPEED The USB_BUSIFFN_IS_DEVICE_HIGH_SPEED routine returns TRUE if the device is operating at high speed. |
| PUSB_BUSIFFN_QUERY_BUS_INFORMATION The QueryBusInformation routine gets information about the bus. |
| PUSB_BUSIFFN_QUERY_BUS_TIME The QueryBusTime function gets the current 32-bit USB frame number. |
| PUSB_BUSIFFN_QUERY_BUS_TIME_EX The QueryBusTimeEx routine gets the current 32-bit USB micro-frame number. |
| PUSB_BUSIFFN_QUERY_CONTROLLER_TYPE The QueryControllerType routine gets information about the USB host controller to which the USB device is attached. |
| PUSB_BUSIFFN_SUBMIT_ISO_OUT_URB This callback function is not supported.The SubmitIsoOutUrb function submits a USB request block (URB) directly to the bus driver without requiring the allocation of an IRP. |
| USBC_START_DEVICE_CALLBACK The USBC_START_DEVICE_CALLBACK routine allows a USB client driver to provide a custom definition of the interface collections on a device. |
Structures
| USB_BUS_INFORMATION_LEVEL_0 The USB_BUS_INFORMATION_LEVEL_0 structure is used in conjunction with the QueryBusInformation interface routine to report information about the bus. |
| USB_BUS_INFORMATION_LEVEL_1 The USB_BUS_INFORMATION_LEVEL_1 structure is used in conjunction with the QueryBusInformation interface routine to report information about the bus. |
| USB_BUS_INTERFACE_USBDI_V0 The USB_BUS_INTERFACE_USBDI_V0 structure is provided by the USB hub driver to allow USB clients to make direct calls to the hub driver without allocating IRPs. |
| USB_BUS_INTERFACE_USBDI_V1 The USB_BUS_INTERFACE_USBDI_V1 structure is provided by the USB hub driver to allow USB clients to make direct calls to the hub driver without allocating IRPs. |
| USB_BUS_INTERFACE_USBDI_V2 The USB_BUS_INTERFACE_USBDI_V2 structure is provided by the USB hub driver to allow USB clients to make direct calls to the hub driver without allocating IRPs. |
| USB_BUS_INTERFACE_USBDI_V3 The USB_BUS_INTERFACE_USBDI_V3 structure is provided by the USB hub driver to allow USB clients to make direct calls to the hub driver without allocating IRPs. |
| USBC_DEVICE_CONFIGURATION_INTERFACE_V1 The USBC_DEVICE_CONFIGURATION_INTERFACE_V1 structure is exposed by the vendor-supplied filter drivers to assist the USB generic parent driver in defining interface collections. |
| USBC_FUNCTION_DESCRIPTOR The USBC_FUNCTION_DESCRIPTOR structure describes a USB function and its associated interface collection. |
