The only frequency supported by SAM-BA Monitor to allow USB communication is a 12 MHz
crystal or external clock.
The device uses the USB communication device class (CDC) drivers to take advantage of the
installed PC RS-232 software to talk over the USB. The CDC class is implemented in all
releases of Windows
www.usb.org, describes how to implement devices such as ISDN modems and virtual COM
ports.
