title: How to make usb port static?
body: <p>Is there's any way I can fix usb port in Debian linux? For instance, I plugged in usb to serial cable(Cable A) and Debian assigned it to /dev/ttyUSB0. After that i plugged in another usb to serial(Cable B) and it was assigned to /dev/ttyUSB1. </p>
  
  <p>I understood that if I want Cable A to always be assign to /dev/ttyUSB0, I have to plug it in before I insert Cable B. Are there any alternatives if I want Cable A to always be assign to /dev/ttyUSB0 and Cable B to /dev/ttyUSB1 regardless which cable I plug in first or whatever USB port I plugged it in?</p>
  
  <p>I'm open to any suggestion on how to do this and I can write c++ to handle this if needed.</p>
