I just got my Deck Legend - Ice Keyboard! keyboard back from repair where they changed the keyboard from usb to PS/2.
And I have discovered something new.
With my usb version if I had the keyboard lights turned off you could not see if the Caps button was locked no red light. But I just hooked up the replacement with PS/2 and to my surprise even with the keyboard lights turned off the Red light still shows when I have the Caps key locked.
Why does it work with PS/2 and not usb?
Anyway this makes me very happy I changed to PS/2 because the one thing I did not like about this keyboard was that you could not see the Caps lock red light when the keyboard lights are turned off.
