Hmm! I have a USB2 MP3 player that takes minutes to be recognized if I attach it to that USB 1 port. If I connect to the USB2 Port, almost instant detection.
I hate marginal equipment combinations (one may JUST meet the Minimum values, the other is hovering near the Maximum values.
is waiting to happen
BTW All my computers are close to 10 Years old, and all have USB2 ports (the 12 YO has just 2 USB 1 ports)
