2.4.15 Mini PCIe slot (CN27)
CN27 is a PCI Express Mini Card connector 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.
