I am still having problem with the led brightness control (only two levels). FYI, I am using the latest firmware.
Can someone tell me how many brightness levels are there?
I think the leds I am using may be the cause of the problem. What's the preferred voltage range for the leds?
EDIT: BTW, I think I find a bug: the number lock indicator lignt would stay the same after I press the led ctrl key to turn off the leds. And when the leds are off, the num lock light cannot be swithced on/off, but the caps lock light can. Not really a big problem.
