Reminds me of the first time I built a PC. I had an MS Mouse 1.0 which simply didn't work with the motherboard. I returned the board to the manufacturer twice, insisting there was a defect. They told me there was nothing wrong. Extremely frustrating.
So, I finally tried an MS Mouse 2.0 and it worked just fine. Who knows why Asus would make a motherboard that won't work with Mouse 1.0...
Never give in--never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
Winston Churchill, 1941.
