title: How to assign user defined name to USB CDC Serial ports?
body: <p>I'm using USB Modem with my Linux board, and Kernel is creating 4 Virtual(CDC-ACM) serial ports when i connect the modem. and the Serial port name asr like ttyUSB0 - ttyUSB3. But these assigned names are not always same. If i have connected some other USB CDC devices already, then Kernel is assigning a different set of names, like ttyUSB4-ttyUSB7. This behavior is affecting my program, I have to change the Port numbers each time. </p>
  
  <p>So is there any way to assign user defined names to Modem USB CDC ports, based on the Device ID of the Modem?</p>
