iPod Touch will Not Charge/Connect to Computer

So, my iPod Touch 4G running ios 5.1.1 will not charge/connect to iTunes on my computer. It charges everywhere else but not on my computer. I even tried another charger. My computer says all my devices are up to date. But I can't find the 'Apple Driver' someone told me to look for! I have looked at 10+ pages on google but nothing works! Help?
