Hi again

Quick update: Using the Device Monitoring Studio software I was able to confirm that both sending and receiving data to EP2 IN/OUT seems to work fine.

I spent some time modifying the USBD example to include a separate interface with two endpoints (EP2 IN and OUT).

I haven't been able to properly test these endpoints by setting up an application on the host to send or receive data from them, but based on the log the code seems to enumerate successfully, and I can send data on EPIN2 without problems.

You can have a look at the example here if you're interested:

The listing from the device manager doesn't provide a lot of details. You mean you want to create a HID compliant vendor defined device?

As I mentioned in another case I will try to create a modified example based on the usbd example, with one more interface set up for custom HID communication.

Sorry for the slow response. I didn't realize at first that you were using the standard usbd example as a starting point. On second thought I think this is an easier example to modify than the hid_generic example.

One comment I have looking at your code is that you don't seem to set up a HID report descriptor for your out endpoint. Is this intended?

Also, can you let me know what kind of issues you see when you run the example?

Do you get some error message when you run the code, or do you have problems writing to the device?

How do you plan to interface to the device from the host side?

Best regards
Torbjørn

I need some more time to set this up, but will try to get back to you in a day or two.

How to add OUT reports and endpoints in the HID generic example?

Hi Shen

Which SDK example have you used as a basis for your project?

Can you tell me a bit more about the issues you are seeing?

The HID generic example is probably the best place to start if you want to add OUT reports and endpoints.
