Randy,
I'm not sure if this would cause a problem, but as it would be simple to check could you do the following: (1) rename the ~/.ti folder to to something else (IE, .ti-temp), and (2) make sure the folder ~/ti/CCSExternalReferences and all files in that folder are globally readable, and (3) make sure the permissions on the udev rules file itself are at least 644 . FYI, the script that creates the rules file is located in <install_dir>/ccsv6/install_scripts.
