USB hid-keyboard example ""USB HID device is not ready"

[srubin-ns]

Hello. I have been playing with the HID keyboard example (./samples/subsys/usb/hid-keyboard) and it's not running correctly. Code was compiled for the nRF7002-DK board (-b nrf7002dk/nrf5340/cpuapp). Here is the output from the terminal:

*** Booting Zephyr OS build v4.0.0-1487-g595d81a941c5 ***
[00:00:00.253,509] <inf> main: HID keyboard sample is initialized
[00:00:10.770,782] <inf> main: USB HID device is not ready
[00:00:10.996,856] <inf> main: USB HID device is not ready

The two "USB HID device is not ready" appear when the user button is pressed.

I have tried other boards, computers, etc, and get the same results. Results are also the same forwarding the USB device to WSL with USBIPD.

Has anyone else run this example recently?

Any ideas?

Thank you!

Hello,

You can try to run "nrfjprog --recover" once. I built the hid-keyboard for the nrf5340 and it seems to work here, though you likely need to plug in and out the USB cable once, and also make sure that your USB cable have data lines.

I notice you are using vanilla zephyr directly (not nRF Connect SDK). In that case you may need to rely on zephyr community support if you don't want to switch to nRF Connect SDK (until we have caught up).

Kenneth, thanks for the tips. I did try to recompile with nRF Connect SDK, at least I think I did. I also ran the ""nrfjprog --recover" command and there was no change. 

Below is the complete "from scratch" build process. Can you please do a sanity check on this? Thank you.

I guess I should redo the test, I might have missed something, and I did use the nRF5340-DK (not the nRF7002-DK). But you can confirm you physically removed the USB cable from the nRF USB port, and re-inserted it after programming?
