I want to move my tower away from my desk and use a USB hub or hubs for all my USB devices. I remember, however, from past experience that hubs do not always work the way you want them to. Some devices work intermittently , drop off the hub, come back on, and other devices just don't work properly unless connected directly to the computer. Do hubs exist that are reliable enough to make it equivalent to plugging a USB device into the back of your computer? Thanks in advance.
