So given that the uMBP has two horizontally oriented USB ports, when I plug in the receiver for my Logitech keyboard and mouse, and my external monitor via mini-dp, it leaves very little room to use the other USB port. My solution for this was to use a powered USB hub for everything, and then just plug the hub into my MBP. At any one time, I will always have plugged into the hub my logitech receiver, and my external hard drive. Often I will also have plugged in an iPod or two, and a video camera, and sometimes a digital still camera. When I have just the external hard drive plugged in, and I want to move the computer without shutting it down, I will eject the hard drive, and then just unplug the hub. However when I have more than one device, I have to eject each one. Is there a way I can streamline this process? Or better yet, despite the warning, and I really doing potential harm to any of the devices by just unplugging the hub without ejecting each device? Thanks for your help all.
