I have a B&W G3 350. I have purchased the new apple pro extended keyboard and optical mouse to update the small ones. Using any version of OS 9 (I have tried 9.0, 9.04, and 9.1), after turning on my computer, the keyboard and mouse are dropped. I have them plugged into the back of the machine and not a hub. Whenever I restart or anything, they work just fine, but they never work when turning on the machine (cold boot). Can someone please help. I've tried everything I can think of--zapping pram, etc. I am clueless. Thanks for any help in advance.
