2nd Gen iPod shuffle is not recognized by iTunes or computer

I read the other posts about people's 2nd Gen Ipod shuffles not being rcognized by iTunes or their computer, but none of them seemed to fit.
I have had my iPod shuffle for less than a week. Last time I had my iPod connected to iTunes in the "Settings" section I clicked "Do not automatically open iTunes and synch with iPod" or something along those lines. I assumed this meant iTunes wouldn't always open when I plugged it in to charge it.
However, now when I plug it into my computer, iTunes does not recognize it and I get a message from my computer that there is a "USB Device Not Recognized" and the error message reads: "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." It shows up as an "Unrecognized Device". I have tried plugging it into a different USB port, and I have also downloaded the "Ipod Reset Utility" to try to reset it to it's factory settings, in case that would allow it to synch up with iTunes again. This does not work. Does anyone know why this is happening, or how I can get iTunes to recognize my iPod again? Thank you!
