# IGameInputDevice::GetRevisionNumber

> Gets the hardware revision number of the input device.

Gets the hardware revision number of the input device.

## Syntax

```cpp theme={null}
uint16_t GetRevisionNumber();
```

### Parameters

This method has no parameters.

### Return value

Type: uint16\_t

The hardware revision number of the device, or 0 if the device doesn't report one.

## Remarks

The revision number distinguishes between hardware revisions of a device model that share the same vendor ID and product ID. For USB and HID devices, this is typically the revision number that the device reports to the operating system.

The revision number doesn't change for the lifetime of the device object.

In GameInput v3 and earlier, this information was available from the `revisionNumber` member of the [GameInputDeviceInfo](https://docs.xbox.com/reference/input/gameinput/deprecated/structs/gameinputdeviceinfo.md) structure returned by [IGameInputDevice::GetDeviceInfo](https://docs.xbox.com/reference/input/gameinput/deprecated/interfaces/igameinputdevice/methods/igameinputdevice_getdeviceinfo.md).

## Requirements

**Header:** GameInput.h

**Library:** gameinput.lib

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
