The LPC1114 on the UMFT12XEV board is pre-loaded with firmware supporting Communication Device
Class (CDC class). The major OSs support the CDC protocol on their USB stack to use serial port
communication, allowing PC’s to access the CDC device through a virtual COM port (VCP) without
developing a new driver.
Linux recognize the CDC device as /dev/ttyACM# (# denotes a number). The driver is loaded
automatically when the device is connected.
Mac OS recognize the CDC device as /dev/cu.usbmodem# (# denotes a number). The driver is loaded
automatically when the device is connected.
Windows has a CDC protocol driver (usbser.sys) to generate VCP. However, it requires a “Setting
Information (INF)” file at the first connection. The required INF file can be download from FTDI website
