I downloaded the FLIP software. I then shorted out the required pins to put it in DFU mode. It did not work at all. I don't see it in devices. It still does the same thing.
I went to the device manager and I clicked on Install Legacy Device. I found the Arduino UNO R3. Now I see the Arduino UNO R3 and it has a yellow triangle. I believe I can see it now because of the website you referred to http://arduino.cc/forum/index.php/topic,118440.msg891474.html
because it installed the R3 drivers. It says the drivers are up to date but still has the yellow triangle. Hmm.... I'm so stumped now.
