Do you have 5V on the pins on the Octdopus you're trying to connect to? Time to pull out the multimeter!

so just to be clear. the power is supplied buy the usb? and the jumpers are for sending a signal to let the rpi know to use the usb?

no, the power is supplied by the Octopus, USB is for communication.
