Yeah, everything in this space is so horrible. I have a laptop with an RGB keyboard. Its default settings are bright blue LEDs for every key. The only way to turn it off is to boot Windows 10 and start an incredibly shitty manufacturer program that takes over one minute to display a window on the screen and even longer to become interactive.
It was so bad I reverse engineered it in order to make a Linux version. Couldn't figure out how to intercept the I2C/ACPI/EC stuff but it turned out the LEDs were implemented via USB. Wireshark gave me all the data I needed to write a free software replacement.
There's a feature on the keyboard that lights up keys when they're pressed. I thought it was implemented in hardware... I was wrong. They made a driver for this. It runs in kernel mode, intercepts keystrokes and sends commands to the keyboard telling it to blink the specific LEDs. It's such an insane design, I have no idea why they'd do such a thing.
