Same here. I have a PowerMac G5. It often doesn't see the new keyboard either. Pulling out / re-inserting the USB cable two or three times (after powering up & whilst at the login window) usually results in the Mac recognising the keyboard & mouse though. Maybe worth a go with your Mac Mini's?
I don't know if anyone else has noticed this, but what's strange is that when I press the power-key & the G5 fires up, the mouse's laser-light (which is connected to the keyboard as usual) DOES light up. It's only when the Mac begins loading OSX that the mouse-light goes out completely, then after a few seconds it comes back on again - IF, that is, the keyboard & mouse are going to be recognised.... Otherwise, both are dead until unplugging/plugging the USB a couple of times. They are definitely getting power though, because the mouse-light briefly flickers when re-connecting the USB, even if the G5 doesn't see them...
In case it makse a difference, my keyboard & mouse are connected to the G5 via a powered USB hub (haven't had chance to test NOT using the hub), but the old keyboard was wired up the same way & I never had any problems at all.
