Default Epic 4g touch will not detect on windows

Well I was going to root my girlfriends phone today, but I cant. Now before you tell me to use a search button, listen.

I tried looking. I've tried every solution I found. Here's what's going on.

I downloaded kies, then connected phone, phone started charging but no detection on windows. I tried a different cable, still nothing.. Uninstalled kies, restarted phone and computer, reinstalled kies and hooked the phone back up. Same deal, charge only but no detection on windows

So I tried another computer, different cable again. Same problem. Charge only, but no detection on windows. I looked at the charging port, no bent, discolored pins. It will charge on an ac charger as well. I have tried everything I know, it won't even detect Odin mode.

Any suggestions?
