I would like to know if there is an example project of USB composite (CDC+HID) for STM32L562.

I have two independent projects HID and CDC which work correctly. But when I want to merge the two projects to have on composite USB device, the HID does not work correctly, it stucks. Only the CDC works fine.

Hello @MOsta.1 ,

There are only independent projects within STM32CubeL5 package.

So, I suggest you to debug, localize where the code hangs, and identify what is the problem that you see and when it occurs.

There is a demo example here that might shed some light on the matter.
