Windows 7 does not recognize my iPod touch 5--doesn't even charge the device. HELP!

My computer at work will not recognize my iPod touch generation 5. I've had increasing problems and now today when I plug it into the USB port, it will not recognize it.

I've uninstalled all the Apple, iTunes etc. software and reinstalled, I've rebooted the computer 3-4 times. I've uninstalled and reinstalled the USB driver.

It will not work. Ideas?
