Perhaps try changing the COM port number of the other device?

Yes, I do, but sometimes it is also devices without COM port choice. Fortunately on my work computer I can do it. Thank you.

Hi Dimitry,

You are right.. the port numbers cannot be changed in our PC as well. We were not aware of this and thankyou for letting us know. We don't usually change the COM port number when testing applications and changing the COM port number of the DKs seems to work perfectly fine. I assume that it is because it's the nRF connects driver that connects the PPK, but with DK, it is a generic windows serial driver.

Perhaps try changing the COM port number of the other device?

Very strange, but I have exactly the same picture on both Windows 7 and Windows 10 computers (even on Win11) with my PPK2 device. I see "CDC ACM" driver without any dialog for change port. When I try tu update driver to "nRF5_SDK_17.0.2_d674dde\examples\usb_drivers" I got message that the same driver is already installed.

Hey Dimitri,

I believe this is a problem since you are using Windows 7. In Windows 8 and later versions, there is a default driver for USB serial communication, usbser.sys driver, and changing the COM port seems to work fine. When you are using Windows 7, CDC ACM driver installation is required. Did you install the Win7 driver ? kindly refer this for instructions.

I know how I can change the Port number for Prolific and other virtual COM port devices, but I can't find the same possibility for nRF Connect USB CDC ACM. For example now it is COM5, what can I do for assign it as COM15, is it possible?

Hi Dimitri,

Kindly take a look at this for changing the port number on Windows.

After some reinstalling of the nRF Connect for Desktop my , Windows successfully reinstalled the driver, but there was still a problem with the COM port number. How can I change it?
