Linux: cut power for LED lights on my CM STORM TK?

[Ansich]

So my keyboard has this annoyance, that the arrow keys on the NumPad are always on by default (except if NumLock is engaged). However, if I unplug my laptop from AC and let it run on battery, then reconnect it, the lights stay off. They turn back on if I press a function button that lights something up on the keyboard (like Caps Lock).

Is there any way to control power management to the keyboard from the command shell? If that is the case I can probably write a script to automate it. I guess something could be found in /dev? But I'm pretty clueless to be honest:(

Can you plug it in and out and run a dmesg?

Sure, this is the relevant output:

OK, nothing special there. Can you try xset and see what happens?

It doesn't do anything. The xset -q gives:

Could I somehow monitor what happens when I turn on/off the backlights of the keyboard or press Num/Caps Lock? Perhaps that might be a clue as to what exactly controls the power distibution to the keyboard?

on the same computer, does it fully work off that same port, on windoz?

[Ansich]

It should, I don't remember it ever not working, but it is true, that I very seldomly log in to my Windows OS. I will try that in the evening and report back if there are any issues.
