2.4.19 PCI-Express Mini Card Socket: CNS1 (Optional)
CNS1 is a PCI Express Mini Card socket, support both a x1 PCI
Express link and a USB 2.0 link. A PCI Express Mini Card can use
either PCI Express or USB 2.0 (or both). USB 2.0 support will help
during the transition to PCI Express, because peripheral vendors will
need time to design PCI Express into their chip sets. During the
transition, PCI Express Mini Cards can be quickly implemented using
USB 2.0.
This connector is optional. It is not mounted by default design.
