Two things come to mind:

1. If you're plugging in the keyboards to a USB port on the case, make sure these ports have been connected to the mobo; or

2. try plugging the keyboards into the motherboard

If you've tried 2, and that fails, you could have a bad mobo. Also, try other USB devices into the USB ports to see if said devices power-up.
