This Hub offers the advantage of absolute security on its seven ports. My Epson printer, especially, left without complaining direct connection with the computer and now goes through this relay (on other Hub I have, the risk is great to see it stop without warning in the middle of his task) . As for the mini Freecom disk, rather demanding in energy and for which, specifically, I bought this Hub, he "goes" straight to the screen and works without incident. However, it seems that the "D-Link is not made to be used itself in cascade. If I plug in a non-powered hub behind him, the energy passes and the second most Hub remains inert. I ' have not tried to see what happens when connected upstream, for my Mac, like all computers, has multiple USB ports, so I installed my waterfall in parallel with the D Link. This time she only needs two "floors", and I can effectively connect my empty cards or the camera itself at the end of the series connections. The reason for all this? Rabies complicate what is simple? I just twelve permanently connected devices, whether they are working or not. In addition, a Mac as the one I use is designed largely based on "design". It is thus failing to offer all its ports, USB or Fire Wire, behind the screen, and to make strong and inconvenient access.
