Example CDC ACM in 15.3

[Jimmy@zone]

When building the sample code using the latest SDK I do not see the device in the device manager and after a while I get this error:

Any hints on what is wrong ?

Are you by any chance using Windows 7? If that is the case, you will need to run step 4 here. I have tested with a 52840 DK on Windows 10 & did not receive any issues at all. Are you by any chance using a usb hub? Maybe it would help to connect directly to your PC instead?

I have also noticed once in a while that I receive issues seeing my dev kits in the device manager & connecting to them via J-Link. The only workaround to this issue I have found is to restart the computer.

I am using Windows 10 and switching back to 15.2 instead makes it work directly with out any issue. Rebooting the pc didn't help.

Any update or a guest when this might be fixed?

Hi Jimmy, I have talked to another application engineer & he did not see this issue on his Windows 10 machine. Could you test on another PC to see if that issue appears there?

Did you donwload it from www.nordicsemi.com/.../nRF5SDKforThreadandZigbeev300d310e71.zip

Ill try to find a second window10 box to test on.

Nope, downloaded the sdk v15.3 from here. Could you try the example there, if you have not done so already?

Tested the new url with the same result, still looking for a new windows 10 that I can play around with.

Here are the event logs for the device when I plugg in the usb cable to the "serial usb port".
