Okay! So I have had this Arduino Rev 3 for a month now and I have gotten nowhere, every time I plug it in I get the same thing Unknown USB Device (Device Descriptor Request Failed). I have tried to do the reboot, I have gotten 2 different cords, and I am using a 2.0 USB port. I'm using windows 8.1 and I have gotten nowhere. Trying to use this device has frustrated me to no ends and I have found little help from the internet and no help in person. No one knows how to use this even after checking with the people at Radioshack, Best Buy, etc. The few computer guys know nothing about how to fix this troubleshoot problem or have even heard of arduino. I'd greatly appreciate any help that different from the normal corrections. Thanks for any help guys.
I wonder if Windows 8.1 needs the same installation step as Windows 7, Vista, or XP:
