I moved your post into its own topic as it was unlikely related to the topic you were posting in.

Can you give some more details;

Have you ever been able to connect or is it the first time you have tried?

What error message do you get?

Does your ECU show up in the comports section in windows device manager similar to my picture below?

I think it would be best to try and get link support to remotely log into your computer and check your installation of the software as well as settings for the drivers.  You've installed the latest version of PC Link for the G4x, correct?  Any error messages during installation?

Have you tried anything like this: https://www.dell.com/community/Desktops-General-Read-Only/No-Ports-listed-in-Device-Manager/td-p/3777524

It seems weird there are no ports showing in the device manager.

What shows up under other devices on your device manager list?

I guess it is not just about the 'Ports (COM & LPT)' not showing in Device Manager... I also don't get any device plug-in notification sound whenever I connect the USB cable from the ECU. So having to manually add the COM port does not help either.

The option to enable/disable 'Ports' is no longer available in UEFI only BIOS.

Perhaps doing the opposite of what this article recommends would help?

Your uknown usb device is likely the usb-serial com port emulator for the Link ecu, though.  Does that change when you plug in or unplug the Link ecu and scan for hardware changes?

The Link G4x doesn't like the latest version of windows either........ended up using an old laptop to connect to the ECU.
I've commented on another post as it seems as it's after the latest software release.......Not had any luck connecting to the new laptop yet, but waiting to see what's happening with the ECU fix first so hopefully this will be sorted pretty soon for a PNP system.

The status of the 'unknown USB device' does not change whenever I plug in/out the USB from the ECU...
I've also have tried the procedure on the article you have provided on the link, and it didn't help either. :(
