A rust library to control the RGB LEDs on the back of the LG UltraGear 38GN950-B monitor. It may work on similar models, but I haven't tested it on anything else.
Only tested on Linux, but should work on anything that supports libusb.
On Linux you will either need to be root, or add this udev rule to grant every user write access to all LG USB devices
