Power down this instance.
Disable interrupts and stop sending events. This method can be used for temporary power-saving; This call can allow USB to be temporarily disabled to permit power saving. However, it is up to the user to make sure all the transfers have concluded (for example when USB power is lost). USBDevice::connect can be used to resume USB operation.
