PC shows driver wrong when I try to combine HID Mouse and keyboard... How to make a HID device combined with mouse and keyboard???

Sad~Sugar

Hi I have a project to use HID mouse and keyboard at the same time, I have tried , but it really can't work well. I've read the similar question and you don't give the clearly answer. So please help. Here are Link about the similar question and unsolved either.

The related code I coded are as follows:

#define INPUT_REPORT_COUNT              4                                           /**< Number of input reports in this application. */

#define INPUT_REP_REF_MOVEMENT_ID       2                                           /**< Id of reference to Mouse Input Report containing movement data. */
#define INPUT_REP_REF_MPLAYER_ID        3                                           /**< Id of reference to Mouse Input Report containing media player data. */

    Hi Sad~Sugar,

    Which error do you have when you connect to the PC ? I suspect the structure of the report descriptor having problem.

    I'm not an expert with HID but can you have a look at this report descriptors I attached here? It seems that you need an usage page for the keyboard before declare the usage. This is the descriptors we used for the smart remote 2. In that reference design we combine both mouse and keyboard in one device.

    Thank you very much. Yes, my descriptors are wrong, but it still don't work after I correct it according to your file, PC's progress bar stopped for a very long time after I try to connect it, and shows driver wrong after the progress bar finished, I don't know what is the exactly problem. I think it's not only because the descriptor, but also some other settings wrong. I have solved the problem by creating two HID services in one device, it works.
