USB Ultra IR-Receiver v2.0 to PC remote control and power ON - OFF

This Atmel IC, is clocked in the circuit with a 12 MHz quartz and provides a communication between the Infrared receiver and the PC, so that this signal can being processed by infrared receiver programs like Girder. As soon as a valid RC5 signal of the remote control arrives, a green low current LED with a 1. 5K resistance and the opto coupler with

a 390 ohm resistor is supplied with power.
