Hi all, Can anyone explain to me the difference between the square shaped USB connectors and the ones which are thinner and more rectangular? Most of the ports on my PC here are the latter type, which is fine because things like my Book Courier and Sarah's Palmtop plug up via the rectangular type. But I have a 4-way hub which only seems to accept the fatter square ones. However, I don't have any pieces of kit which rely on these. Does this mean the hub is of no use? Cheers now. Ian
