The Maestro’s two virtual serial ports can be used in Linux without any special driver installation. The

virtual serial ports are managed by the cdc-acm kernel module, whose source code you can find in

your kernel’s source code drivers/usb/class/cdc-acm.c . When you connect the Maestro to the PC,

the two virtual serial ports should appear as devices with names like /dev/ttyACM0 and /dev/ttyACM1

Port. You can use any terminal program (such as kermit) to send and receive bytes on those ports.
