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 ?

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".

I tried a different New Windows 10 pc.

Downloaded the latest Segger studio and installed the Nordic addon.

Downloaded the SDK

Connect the Dev kit, it installed 13.2 serial port ok, it was installed.

Build the C:\nRF5_SDK_15.3.0_59ac345\nRF5_SDK_15.3.0_59ac345\examples\peripheral\usbd_cdc_acm\pca10056\blank\ses

Start it on the Dev kit

Efter a few secons the error appers and a broken device is show in device manager.

Unknown USB Device(Device Descriptor Request Failed)

Sorry for the delayed response. I have tried this example again & unfortunately I can still not replicate the issue. After a bit of setup time, I can see the JLink CDC UART Port in the device manager of Windows. Which version of the 52840 DK do you have? Do you have another 52840 DK that you could test with? Are you connecting one USB cable to the J2 on the DK & one other USB cable to the nRF USB connector on the DK? Is the nRF Power Source switch in the VDD position? These two cases may also be helpful: link 1, link 2.
