This header is used by USB driver reference. For more information, see:
usbuser.h contains the following programming interfaces:
IOCTLs
| IOCTL_GET_HCD_DRIVERKEY_NAME The IOCTL_GET_HCD_DRIVERKEY_NAME I/O control request retrieves the driver key name in the registry for a USB host controller driver. |
| IOCTL_USB_DIAGNOSTIC_MODE_OFF The IOCTL_USB_DIAGNOSTIC_MODE_OFF I/O control has been deprecated. Do not use. |
| IOCTL_USB_DIAGNOSTIC_MODE_ON The IOCTL_USB_DIAGNOSTIC_MODE_ON I/O control has been deprecated. Do not use. |
| IOCTL_USB_GET_ROOT_HUB_NAME The IOCTL_USB_GET_ROOT_HUB_NAME I/O control request is used with the USB_ROOT_HUB_NAME structure to retrieve the symbolic link name of the root hub.IOCTL_USB_GET_ROOT_HUB_NAME is a user-mode I/O control request. |
| IOCTL_USB_USER_REQUEST The IOCTL_USB_USER_REQUEST I/O control request is available to both user-mode applications and kernel-mode drivers. |
Structures
| USB_BANDWIDTH_INFO The USB_BANDWIDTH_INFO structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve information about the allocated bandwidth. |
| USB_BUS_STATISTICS_0 The USB_BUS_STATISTICS_0 structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve bus statistics. |
| USB_CLOSE_RAW_DEVICE_PARAMETERS This structure is not supported. The USB_CLOSE_RAW_DEVICE_PARAMETERS structure is used with the IOCTL_USB_USER_REQUEST I/O control request to close raw access to devices on the bus. |
| USB_CONTROLLER_INFO_0 The USB_CONTROLLER_INFO_0 structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve information about the USB host controller. |
| USB_DRIVER_VERSION_PARAMETERS The USB_DRIVER_VERSION_PARAMETERS structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve version information. |
| USB_PASS_THRU_PARAMETERS The USB_PASS_THRU_PARAMETERS structure is used with the IOCTL_USB_USER_REQUEST I/O control request to pass a vendor-specific command to the host controller miniport driver. |
| USB_POWER_INFO The USB_POWER_INFO structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve device power state that the host controller power policy specifies for the indicated system power state. |
| USB_UNICODE_NAME The USB_UNICODE_NAME structure contains a Unicode string that specifies a symbolic link name. |
| USBUSER_BANDWIDTH_INFO_REQUEST The USBUSER_BANDWIDTH_INFO_REQUEST structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve information about the allocated bandwidth. |
| USBUSER_BUS_STATISTICS_0_REQUEST The USBUSER_BUS_STATISTICS_0_REQUEST structure is used with the IOCTL_USB_USER_REQUEST I/O control request to retrieve bus statistics. |
| USBUSER_CONTROLLER_UNICODE_NAME The USBUSER_CONTROLLER_UNICODE_NAME structure is used in conjunction with the IOCTL_USB_USER_REQUEST I/O control request to retrieve the USB host controller driverkey name. |
| USBUSER_GET_DRIVER_VERSION The USBUSER_GET_DRIVER_VERSION structure is used with the IOCTL_USB_USER_REQUEST I/O control request to read driver and interface version information. |
| USBUSER_PASS_THRU_REQUEST The USBUSER_PASS_THRU_REQUEST structure is used in conjunction with the IOCTL_USB_USER_REQUEST I/O control request to send a vendor-specific command to the host controller miniport driver. |
| USBUSER_POWER_INFO_REQUEST The USBUSER_POWER_INFO_REQUEST structure is used in conjunction with the IOCTL_USB_USER_REQUEST I/O control request to retrieve power policy information concerning the relationship of a specific system state to the power state of the host controller and the root hub. |
| USBUSER_REQUEST_HEADER The USBUSER_REQUEST_HEADER structure is used with the IOCTL_USB_USER_REQUEST I/O control request to send a user-mode request to the USB host controller driver. |
Enumerations
| USB_USER_ERROR_CODE The USB_USER_ERROR_CODE enumeration lists the error codes that a USB user-mode request reports when it fails. |
| WDMUSB_POWER_STATE The WDMUSB_POWER_STATE enumeration indicates the power state of a host controller or root hub. |
