Thanks ，The problem has been solved after replacing the board. nRF52840-DK is ok.

There seems to be a problem on my nRF5240-PDK.

Hi,

It looks like you are sending HID data prior to eventually the USBD interrupt fires after interrupts are enabled; then ending up in the while-loop.

Do you have preprocessor defines "DEBUG_NRF" and "DEBUG" set in your project? If not, could you please set these?

I do not see anything related to ESB in your stack trace, but do note that the radio and esb evt handler runs on isr priority 1 and 2 by default, while your usbd runs on 6 (sdk_config.h::USBD_CONFIG_IRQ_PRIORITY)

How long do you need to run the device before this occurs?

Have you tried to run this on a nRF52840-DK and see if the same issue occurs then?

Kind regards,

Håkon
