I have the same problem. But I read that you can patch the driver (http://hipstercircuits.com/reading-analog-adc-values-on-beaglebone-black/) but I dont know how to do it. Any body know how to use the adc-patches<http://hipstercircuits.com/wp-content/uploads/2013/05/adc-patches.zip> files?
Thanks!!!
