Not saving the LED settings is pissing me off.
It looks like the onboard electronics turn off the LED driver circuitry when the USB host disconnects, so it won't stay lit when the computer is off even when the USB port is still supplying stand-by power. When the host connection is restored, it still resets the LEDs, even though power was never lost! This is just weak!
I can control the brightness and LED mode with a microcontroller, but it won't work after a soft reboot or with a system supplying stand-by power. This is because the keyboard is 'intelligently' pretending to turn on and off based on the data connection to the host. I'm using the application of power to the USB port to trigger the microcontroller, but power is never actually lost in typical usage, so the microcontroller never knows when to reapply the settings.
I can only get it to work the way I want by disabling USB stand-by power, or using a USB HID passthrough device, like a complicated micro-controller setup, a USB keylogger, or a KVM. This works by making the keyboard never lose its host connection, and a microcontroller can apply the LED setting at the first power on. The LEDs would be on even when the computer is turned off.
I think I'll just give up and return to the Deck once again. A real shame. This keyboard could have been great.
