Hi,

Indeed gpio #3 controls the led.
I patched ath5k to use it, and led works now fine.


What I dislike is the way led blinks:

While nether I like constant rate blinking implemented in windows
driver, I don't like the fact that led blinks too fast, sometimes the
blink time is so short that led doesn't show full brightness.

I think there should be a minimal interval for blinking.

Also I don't know what is assumed better, when led is always on, but
turns off when active of vise versa?
(Due to short intervals, when I set it for first option, it is almost
always on, and I almost don't see the interval when it is off)


Best regards,
	Maxim Levitsky
