http://lists.gnu.org/archive/html/discuss-gnuradio/2005-02/msg00285.html Basically, adding the following line (without the quotes) to /etc/fstab: "usbfs /proc/bus/usb usbfs devgid=500,devmode=0664 0 0"ode=0664 0 h with "500" changed to the group ID you want to run under. (You can determine your current gid with the "id" command.)
