 ### Using the latest version
 First make sure that you are running the latest version of libhackrf and hackrf-tools. HackRF One, for example, is only supported by release 2014.04.1 or newer.  Then check to see if `hackrf_info` is successful when running as root.  If it is, then your other user is lacking permission.
