# initInputReport

Starts reading the input report from the device.

## Declaration

```occ
virtual kern_return_t initInputReport();
```

## Return Value

Return Value kIOReturnSuccess on success, or another value if an error occurs. See Error Codes.

## Discussion

Discussion This method requests the input report from the USB device asynchronously, delivering the results to the CompleteInputReport method. You don’t need to call this method directly. The service’s Start method calls it when the service first runs, and the service requests new input reports regularly.
