So, odd is also not detecting, its only powered. Are usb ports working?? If no, then southbridge is likely bad.

Your sata lines are not working like sata_txp/n;sata rxp/n on both hdd/odd. I think its bad southbridge which needs replacement. Do check the tiny caps connected on sata lines near connector first.
