I have a weird issue with my Teensy's 3.6. I have two different boards and when I plug the first board to the PC; it will show COM Port 20; if I unplug the first board to plug the second board; then the second board will show as COM Port 20 too (same as the first board). Also, the serial numbers are the same too!
I haven't plug both boards at the same time. Any help will be appreciated.
