Seems this either a typo, or a contradiction:
"The USB 3.0 sockets are backward-compatible with older ... cables"
would mean I can use the old cables for 3.0, but then
"but older USB cables are not forward-compatible with USB 3.0"
says I can NOT use the old cables.
I have no 3.0, but some day I probably will, so I'd like to know what
exactly you mean.

kind regards

michael
