CM1-86DX2
3.7 USB 2.0 Ports
The Vortex-86DX2 contains one Enhanced Host Controller Interface (EHCI) host controller,
which supports up to four USB 2.0 high-speed root ports. USB 2.0 allows data transfers up to
480Mb/s using the same pins as the four USB full-speed/low-speed ports. The Vortex-86DX2
contains port-routing logic that determines whether a USB port is controlled by the UHCI control-
ler or by the EHCI controller.
The CM1-86DX2 uses three of the four ports. They are available on two USB connectors, one
providing two ports and one providing one port. USB 2.0 supports a USB keyboard running
under MSDOS without special driver software.
The fourth USB port is routed to the MiniPCIe socket X10 and requires a USB extension card.
