I have a B&W G3 and a MacAlly iKey keyboard, and occasionally on startup it won't recognize that the keyboard is there. The mouse will work, but when you type it doesn't do anything. When I unplug it from the back and plug it back in it works. What I have done so far, I tried reinstalling the USB drivers from the OS9 CD, that didn't help, reset PRAM, I have even done a clean install. My old Apple USB keyboard will work fine, but I really like my F13-15 keys
