Control usbled devices via node.js on linux, specifically Dream Cheeky webmail notifier devices ( like you might purchase at ThinkGeek or other random gadget places.

We use libudev to find the devices and their sysfs exposed paths to control them. An alternate implementation would have been to use libusb directly.

In order for this to work on your system, you need to set the permissions up correctly. If you put udev-files/99-usblamp.rules in your /etc/udev/rules.d and put udev-files/ in /etc/udev, then you should be good to go. Well, you may also want to invoke udevadm trigger --action=change to force the changes to apply without you manually having to re-plug things. Many thanks to the post at
