I have just a few USB ports on my PC and so I've found that I'm often taking devices in and out to connect other ones. Besides that finally becoming a bother, it also seems to be making the ports looser and not hold the USB cable as tightly as they used to. I thought that getting a USB hub would solve both problems. I saw there are different types of hubs and I don't know enough to know which is the right one to get. Most of what I connect are external hard drives, and a few other things like my cell phone and camera. The PC has USB 2 and Windows 7 home. I'd really appreciate advice of what type and size hub to get. And will using a hub change how what I'm connecting is recognized by Windows?
