2.4.19 PCI-Express Mini Card Socket: CNS1 (Optional)

CNS1 is a PCI Express Mini Card Socket to support both 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 (or both). 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 period, PCI Express Mini

Cards can be quickly implemented by using USB 2.0.

This connector is optional. It is not mounted as a default design.
