USB Serial Device , UART interface comes up as MODEM in Linux machine
I connected my USBSerial Device which is configured as UART to a Linux Machine . The device comes up as MODEM and not as a serial device or COM port . Why?
USB Serial device when configured as UART CDC then it belongs to the CDC ACM Class . A device that belongs to the ACM drivers where intended to work with USB Modem . So any USB device that binds to the ACM driver will come up as MODEM device in Linux machine.
