I have a robot project where I have a Teensy 3.5 'master' controller and two different Teensy 'slave' controllers (one is a T3.5, and the other is a T3.2).  Telemetry from the 'master' T3.5 is connected to my PC over a Wixel RF serial link.

I'm trying to debug a problem where the master controller is supposed to restart the T3.5 slave every time the master is started.  The master pulls the slave T3.5 reset pin low for 150mSec, and then waits until the slave completes its setup() routine.  This isn't working properly for some reason, so I'm trying to monitor the serial output from the slave T3.5 on COM4 while monitoring the master controller on Com6 (the Wixel RF link).  I am using TeraTerm to connect to the slave, and MSVS 2022 to connect to the master.

However, I when I select COM6 in VS2022, it automatically changes to COM4 (or more accurately, to 'Teensy 3.5 at usb:20000/0/0/2/3/2/4/4') after a few seconds.  So, I can't do an OTA rebuild from the VS2022 side while monitoring the output of the slave using COM4, because VS2022/VM won't let me select COM6.

If I disconnect the USB cable to the slave controller, the 'COM4' and 'Teensy 3.5 at usb:20000/0/0/2/3/2/4/4' entries disappear from the COM port dropdown list, but of course then I can't monitor the output from the slave T3.5.

Any idea why VS/VM insists on changing my port selection from COM6 to COM4?

VM 1.2022.0426, VS 17.1.5, Arduino IDE for VS by VM - 19.0
