Unfortunately, a few computer manufacturers exploited an ambiguity in the
USB2 spec. A number of computers were sold as having ports complying with
USB2. Unfortunate buyers discovered that 12 Mbps (USB1 speeds) was the
fastest it would work at. The problem was that Issue 2 of the spec.
included the 1.5 and 12 Mbps operation, but neglected to insist that a USB2
port had to include 480 Mbps as well.
