I have a scanner, printer, superdrive and keyboard all competing for 2 usb ports.

What should I do so that I don't have to keep unplugging and replugging when i want to change devices?

I have an Entrega Hub plugged into my keyboard. My scanner and printer are plugged into the hub and my keyboard and Zip drive plugged into the computer itself. I've never had any problems with any of them. The only thing that I unplug after each use is my scanner and that's just because there isn't an on/off switch. Hope this helps!

Thanks for the tip. I will look into your recommendation. I appreciate that!
