One of two nRF52840 USB sticks DOA

[Keld_Norman]

I have just purchased 2 pcs. nRF52840 - one of them works fine - the other one reports this when i run dmesg on my linux (tested on 2 different systems) "Cannot enable. Maybe the USB cable is bad?", then it reports "attempt power cycle" and repeats the err. 

Thew stick is connected directly to the USB port

The stick is not damaged in any way and the components looks ok when compared to the other stick.

Best regards

Hi,

 

Strange that one works and one does not. Have you tried it on a different PC and/or operating system?

 

Best regards,
