Default Not being recognized in Odin

Ok, So i'm trying to get my device recognized in Odin but to no avail. I've got the USB drivers installed, I've tried multiple USB ports. Windows Vista and 8.1, even multiple versions of Odin and still not being recognized. Yes my device is in download mode. I'm trying to get off Slim Bean 4.4 because I'm getting FC's and the recovery does not work on this ROM. Anyone help me? Thanks
