Iphone 4s does nothing when plugged into computer?

Yes i've tried different usb's, yes i've used different cords, yes i've downloaded and reinstalled the new itunes and updated all the software, yes i've reset my computer, and yes i've tried putting my phone into DFU mode, so please don't tell me to do any of these things.

I just bought this phone like last week too, and it does absolutely nothing when plugged into my computer, but works when it's plugged into the wall. How do I fix this…

Hardware failure.take it to apple

You opened Itunes right? Don't just connect it, make sure itunes is open so its recognizing it.
