[Discuss-gnuradio] usb rights on FC5 and udev

[Matteo Campanella]

Hello, maybe this is not new, but I have found how to avoid the sudo on 
Fedora Core 5 and run usrp python code as a normal user - the file that 
needs to be modified is /etc/udev/rules.d/50-udev.rules, line 308 in my 
fedora core 5 dist:

#####################################
# Persistent block device stuff - end
#####################################

ACTION=="add", SUBSYSTEM=="usb_device", \
       PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; printf 
bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", \
       NAME="%c", MODE="0644"

ACTION=="add", SUBSYSTEM=="?*", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe 
$env{MODALIAS}"

ACTION=="add", SUBSYSTEM=="pcmcia", ENV{MODALIAS}=="*", \
       RUN+="/bin/sh -c 'echo 1 > /sys/$DEVPATH/allow_func_id_match'"


Simply, change the MODE="0644" to 0666 or 0664 (if you want to use groups) 
and, upon creation the udev subsystem will use these rigths to create 
/dev/bus/usb/xxx/xx.
