Subject: [beagleboard] How to add a udev rule to beaglebone ??

First, you should never give RW permissions to everyone, so I would suggest
MODE=³0660² and then add a USB group and add yourself to that group.
Something like this:
sudo groupadd f usb
sudo gpasswd a <yourUserID> usb
Now the rule becomes:
SUBSYSTEM=="usb", ATTR{idVendor}=="24e0", MODE=³0660² GROUP==³usb"

The rule is place in the /etc/init.d/rules.d folder. Use a name like
"99-usb.rules² so that it is the last rule to execute.
After you plugin your USB, run the following command:
dmesg
This will show you info about the usb device. You can also use the following
command:
lshw
or
lsusb
This will show you info about your USB device that you will need in your
rule.
