Changing USB port on QMX


 

I've just inadvertently? connected my QMX to a different USB port on my W11 laptop and it failed to connect the WSJT-X.? What happens is that the different port means that a different COM port is assigned and different USB audio ports.

Is there a way for an individual QMX to retain it's serial and audio port designations if it's moved to a different USB port on the same PC?

What I've found is that a FTDI serial port will do this but most others won't.? It makes things far easier - for the user at least.
And the developer, they stop getting "I can't find my QMX" messages.

I haven’t fully sorted this out but I think that if you assign a com port it survives to any physical port and through restarts. Give this a try:

  1. Open the Device Manager by pressing the?Windows Key?+?R. Type “devmgmt.msc” and press?Enter.
  2. Expand the?Ports (COM & LPT)?section.
  3. Right-click the COM port and select?Properties.
  4. Click the?Port Settings?tab and click?Advanced.
  5. Change the COM port number to an available COM port number.
  6. Reboot
