After reinstalling the HID driver on the PC, the problem was resolved.

Hi.

After I modified as below, sending data from PC to my device via generic HID was successful.

#define REPORT_OUT_MAXSIZE  63	//0

/**
 * @brief Feature report maximum size. HID generic class will reserve
 *        this buffer size + 1 memory space. 
 */
#define REPORT_FEATURE_MAXSIZE  31

/**
 * @brief HID generic class endpoints count.
 * */
#define HID_GENERIC_EP_COUNT  2

/**
 * @brief List of HID generic class endpoints.
 * */
#define ENDPOINT_LIST()                                      \
(                                                            \
        HID_GENERIC_EPIN,                                     \
        HID_GENERIC_EPOUT                                     \
)

However, sending data to PC using app_usbd_hid_generic_in_report_set on my device does not work.

What's wrong with settings?

What exactly do you mean by "I can't do both sending and receiving data". Are you trying to send and receive simultaneously or what? Can you explain in detail what you're trying to do and what problems/errors you're seeing when trying to implement it?

Best regards,
