5.15 Universal Serial Bus (USB)
This CPU board is fitted with a USB Host socket (type A, CN10) and a Function socket (type Mini B, CN11).
USB module is connected to the Host and Function socket and can operate as either a Host or Function
device. However, they cannot be used at the same time. The connection for the USB module is shown in
Table 5-22 below.
