For this IRP, the driver sets the InterfaceType input parameter to GUID_DEVICE_RESET_INTERFACE_STANDARD. To query for this interface, a device driver sends an IRP_MN_QUERY_INTERFACE IRP down the driver stack. However, a platform-level reset should only be used as the final option. If a function-level reset does not fix the issue, then the driver may choose to attempt a platform-level reset. If a function driver detects that the device is not functioning correctly, it should first attempt a function-level reset. The GUID_DEVICE_RESET_INTERFACE_STANDARD interface is available starting in Windows 10. Minimum value is 100 milliseconds maximum value is 30 seconds.ĭeviceResetMaximumRetries: Number of times the reset operation is attempted. Starting in Windows 10, these registry entries under the HKLM\SYSTEM\CurrentControlSet\Control\Pnp key configures the reset operation:ĭeviceResetRetryInterval: Time period before the reset operation starts. The OS will tear down and rebuild the stacks of all affected devices to ensure that everything restarts from a blank state.

This type of reset has the most impact on the system. The reset operation affects a specific device and all other devices that are connected to it via the same power rail or reset line. In this case, the reset operation causes the device to be reported as missing from the bus. ACPI firmware can optionally override a bus driver-defined function-level reset with its own implementation. The bus driver can implement a function-level reset if the bus specification defines an in-band reset mechanism that meets the requirement.

This type of reset has the least impact on the system. The device stays connected to the bus throughout the reset and returns to a valid state (initial state) after the reset. In this case, the reset operation is restricted to a specific device, and is not visible to other devices. Two types of device resets are available through this interface:įunction-level device reset.

The GUID_DEVICE_RESET_INTERFACE_STANDARD interface defines a standard way for function drivers to attempt to reset and recover a malfunctioning device.
