USB CDC ACM

Hi all,

I'm using SDK 15, nrf 52840, win 7,

The USB cdc example works fine for me.

Yet, when I moved the code to my project the driver is not set by win 7.

On device manager I see the device as a "USB composite device".

I used a USB analyzer and found that after few calls the code reaches the function nrf_drv_usbd_setup_stall(); - and I have no idea why.

On the sniffer I see that my code fails when reaching record "Set Configuration (configuration=1) - at this point for some reason the setup in my code reach the stall function.

As I'm not familiar with USB protocol - any help or idea regarding this is most welcome!!!

Regards,

Lior.
