When you say it's "not recognized" please clarify

1. Do you mean when you plug it in Windows gives shows you a USB not recognized message?
2. Are you hearing the USB device connect ding-dong when you plug it in?
3. Try opening Device Manager and watch when you plug it in. Are you seeing a new device appear in DevMgr but just not seeing the disk appear in My Computer and Explorer?
