Hi again

The developer has now created a pull request with the fix for this issue:
https://github.com/zephyrproject-rtos/zephyr/pull/36149

Could you try to apply this fix locally and see if it fixes the problem for you as well?

Best regards

Hi Leo

There is progress, yes, but unfortunately I don't have a fix to share yet.

The developer looking into this claims to have found a bug related to the request handling in the Audio class, but he doesn't yet have a patch to share.

I will ask him for an update tomorrow and let you know what he has discovered.

Best regards
Torbjørn

Hi Leo

I did a test combining the HID mouse and audio examples myself, and I am getting exactly the same results as you. The project enumerates fine, but whenever I try to send anything over HID I get the -11 error message.

I will have to do some more investigation to figure out the root cause, and get back to you.

Hi Torbjørn

After programming headset.zip project to my development kit，The USB Audio Device works while the USB HID are not able to be detected.

And once I pressed the button on the kit to test the hid-mouse, The log came ou like this:

It seemed that the problem of registering the hid device still exited.What is the reason?

Is there a similar way to combine this two samples like the USB HID CDC ACM Application Sample

which can be found under samples/subsys/usb/hid-cdc？If not, What is your suggestion？

Best regards

Leo

And the log came out like this:

It should be possible to combine these two USB classes, yes. Did you remember to register the HID device, as shown here?

If you still can't make it work, are you able to share your project with me so I can have a look at it?

Best regards
