Ok so i actually shutdown my G4 for the first time in a month or so last night. I wake up and turn her on, and mmy keyboard and mouse are not responding. I made sure all the connections were secure but still nothing. I restarted and tried it again.....nothing. So I pulled out the usb cord above it which is the cord to my printer, and they magically work again! But if I put the cord back they stop responding. What the hell is going on here?? I only have to usb ports in the back and now I can only use one? It had never done anything wierd like this the entire time i had my printer hooked up untill now. Also another thing, it is only the printer cable that does this. I tried plugging a mouse into the back and it didnt effect my keyboard at all I had two mice running at the same time because my other mouse is plugged into my keyboard. WTF is going on here?
