Hello,

Thanks for your reponse.

I performed same test on another PC where I have Windows 10 and found no issue. When I plug the cable, the USB is getting recognized automatically and COM port is popping up.

I also tried resetting COM ports as per your suggestion, but no luck.

Is it possibe for you to perform the test on Windows 8.1 at your end?

Thanks,

Krishna

Hello Krishna,

Unfortunately, I don't have access to a Windows 8.1 computer.

Can you please try the suggestions that Stian provides in this thread:

Hi Edvin,

I have installed nRF Connect for Desktop as per Stian's suggestion and the driver "nRF Connect USB CDC ACM" included in nRF Connect for Desktop works and unblocks me for testing

Thanks,

Krishna.
