# Reset

Terminates the device and attempts to reenumerate it.

```
virtual kern_return_t Reset();
```

## Return Value

<doc://com.apple.documentation/documentation/DriverKit/kIOReturnSuccess> on success, or another value if an error occurs. See <doc://com.apple.documentation/documentation/DriverKit/error-codes>.

## Discussion

This method resets and releases the current [`IOUSBHostDevice`](/documentation/USBDriverKit/IOUSBHostDevice) object and all of its children. If the reset and release of the device object are successful, this method creates a new [`IOUSBHostDevice`](/documentation/USBDriverKit/IOUSBHostDevice) object and registers it.

Don’t call this function from the port workloop thread.
