(SOLVED!)Mac Mini doesn't recognize aluminum keyboard startup strokes?
I have a Mac Mini 2006 model with SL installed on it, updated to the latest version. I recently decided to try booting a Linux live CD on the Mac, so I inserted the disc, and restarted the machine.
Interestingly enough, the Mac wouldn't recognize my startup keystrokes. I tried the "C" "Option" and other key combinations, but the Mac continued to boot as normal, straight to my desktop.
I have the new USB wired Apple aluminum keyboard with the two USB 2.0 ports on it, and the Mini simply won't recognize it at startup. The keyboard works fine once I get to the login screen.
To ensure that nothing else was wrong, I plugged in a generic Acer PC keyboard, and rebooted again.
The Mini recognized the keystrokes! I was able to use "C" "Option" and the other keystrokes without fail, and the disc booted properly. But when I used the Apple keyboard, there was no such luck. I ensured that both keyboards were plugged into the same USB port when I tried them both, just to be sure it wasn't a faulty USB port problem.
Could it be that the aluminum keyboard, due to its USB hub, draws too much power from the Mini's power supply, so that it isn't loaded until after the boot sequence is finished? I do have other evidence which may support this theory.
I attached an external USB-powered hard drive to one of the keyboard's ports, and I received the "Device is drawing too much power" error message from the Mini. However, when I plugged the exact same keyboard and external into a Macbook Pro, there was no issue, and the drive was recognized normally.
It could be that the Mini's PSU isn't powerful enough to supply the necessary current to the keyboard's hub, and hence it is ignored at bootup. Is this true, or is there something else I am missing entirely?
Ist dies eine gute Frage?
