Udev problem with Fedora8
 
Hi all,

I am trying to automate my mp3 copying.I used udev to detect specifically
my mp3 card (using USB card reader) and run a script.Although the my rule differentiates the mp3 card and the other thumb drives."mount" does not seem to work in my rule.Please find the udev rule I have written and the behavior

#################################################################

Rule :

#################################################################

# udev rules file by pravin for automation of mp3 copying in phone memory card


SUBSYSTEM=="block" ,ATTR{size}=="3895296",NAME="Test", SYMLINK+="TestUSB" ,RUN+="/usr/bin/usb_script"

###################################################################

Script :usb_script at /usr/bin

###################################################################


mount /dev/TestUSB /home/pravin/USB


touch /home/pravin/usb_script

###################################################################

Behaviour when 4Gb mp3 card reader is connected

###################################################################

sdb1 detection = yes

Test detection = yes

TestUSB detection = yes

usb_script execution = yes (confirmed by execution of touch command)

mount command execution = no


###################################################################

Behaviour when 2Gb Thumb drive is connected

###################################################################

sdb1 detection = yes

Test detection = no (Since size attribute didn't match)

TestUSB detection = no (Since size attribute didn't match)

usb_script execution = no (Since size attribute didn't match)
