3.2.18 Express Mini Card Slot
PCI Express Mini Card connector supports a PCI Express x1 link and a USB 2.0 link.
A PCI Express Mini Card can be applied to either PCI Express or USB 2.0. It
complies with PCI-Express Mini Card Spec. V1.2.
The USB 2.0 support will be helpful during the transition to PCI Express, because
peripheral vendors will need time to design their chipsets to have the PCI Express
function. During the transition, PCI Express Mini Cards can be quickly implemented
by using USB 2.0.
