Attention

There are only two USB ports on the PCIe bus.
If different PCI/104-Express boards with additional USB ports are being used, then the board which will
have the USB ports available must be selected.
Jumpers J4 (USB1) and J5 (USB0) enable or disable the two ports; if they are open, the USB ports are
enabled. Close these jumpers if the two USB ports are already used on another PCI/104-Express board.

It is also possible to enable one USB port on each board but be careful that USB0 is enabled on one
board and USB1 on the other board!
