Is possibile to implement multiple usb hid interface? Kayboard + mouse

Unfortunately I don't think so... the pyb.usb_mode can only be given either hid=pyb.hid_keyboard or hid=pyb.hid_mouse.

This could probably be added though -- look in stm32/usb.c

STATIC mp_obj_t pyb_usb_mode(size_t n_args, const mp_obj_t *pos_args, mp_map_t *kw_args) {

Reading the documentation https://www.usb.org/sites/default/files/hid1_11.pdf regarding the usb hid I found that it is possible to declare more reports but specifying a report id.

Can this feature be used in micropython?

the current implementation of the mouse and keyboard report ignore the report id (as per specification since it is only one report)
How complicated is it to implement this functionality?

Thanks and regards,

It can be done using an adequate HID descriptor.

Have you tried or are you assuming it works?

We are using it on PYBD SW6 to emulate a combination of TOUCH & KEYBOARD. It works perfect.

Can you share an example of hid descriptor?

Can you share an example of hid descriptor and usage with send/recv?
