You wont be able to see the LEDS on the bar. they are IR leds. The human eye can not see them. Using a digital camera, looking at the LCD screen on the camera or taking a pic will show the IR leds (if the bar is on).If you are looking through your viewfinder on your camera to SEE the IR leds you must likely wont see them.
You do not need to connect the Bar to the PC. there is no need for this. The only reason why the wired one connects to the Wii is just for power.
As for the batteries just check to make sure they are good. I have bought brand new batteries that were DOA
