Windows 10: COM port keeps picking up the wrong driver, How to permanently assign the right driver to...

I have the industrial devices that connect to the software using USB cable. There is a problem that every time I connect the USB cable from the device to the laptop, its COM port keep picking the wrong driver SE, even though I just update the driver under Device Manager. I cannot uninstalled the Se driver as it is used for other softwareSo Is there a way to assign the driver to specific COM port so I do not have to update driver every single time?

Wrong driver assigned to device

Device is a CDC ACM device.

When plugged into windows 10 the system driver, usbser.sys is assigned to it rather than the correct driver. Doing an 'update driver' from device manager and selecting manually the correct driver results in the correct driver showing in the list and is
recognised as signed.



If two device are plugged in both get assigned usbser.sys, and both have the same COM number. This is an even bigger fail. The symbolic link must be unique.



Needless to say the driver and installer work perfectly well on all previous windows versions. I have also been writing windows kernel drivers for 20 years, so I know what I am doing.



These are clearly bugs in Windows 10 and need resolving.
