Ah well it is working now, I restarted the computer.... yes, I tried that at least once before posting my message : ) ... I hate computers....
I had followed the http://gnuradio.org/redmine/wiki/1/UbuntuInstall for setting up the usrp group and udev at some point, probably just before my last restart. I think what may have happened was I did not have the usrp group setup the first time I tried usrp_probe and was in a sudo environment, then when I tried it later I was not in the right group. I did not know the PYTHONPATH variable is not available across SUDO, Thanks Marcus. -Jeff Marcus D.
