I just bought an airport extreme, and hooked up my printer and external hard drive to it via a USB Hub (since there is only one usb port in the back). It works but when I transfer files to my hard drive with it in the usb hub, it's very slow. When I put the hard drive directly into the airport extreme without the usb hub its very fast. My question is, is my usb hub crappy, or is this the way it's going to be with EVERY usb hub?
