_DEVICE_INSTALL_STATE enumeration

Description

The DEVICE_INSTALL_STATE enumeration describes a device's installation state.

Constants

`InstallStateInstalled`

The device is installed.

`InstallStateNeedsReinstall`

The system will try to reinstall the device on a later enumeration.

`InstallStateFailedInstall`

The device did not install properly.

`InstallStateFinishInstall`

The installation of this device is not yet complete.

Remarks

The IoGetDeviceProperty routine supplies a DEVICE_INSTALL_STATE enumeration value when a driver requests DevicePropertyInstallState. The operating system uses the value as a hint about the install state of the device.
