Optical flow with APM 2.x

I purchased the ADNS 3080 and have connected it exactly as is shown in the setup guide.  I have flashed the test hex file, but all I see for output is zeros, both in the terminal and with the python script.

When the terminal first opens the test program I see "Failed to initialise ADNS3080".  I'm not sure what else to try.  I've triple checked the wiring.  Has anyone had success with this sensor recently?
