PCI-Express Mini Card Connector

The PCI Express Mini Card connectors with support for 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. 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.
