USB with RL-USB

Hy, i'm starting to program on stm32f407 and I have some problem using USB.

I manage to make simple application with wizard.
But now, i want to make for example an HID Application with more than one endpoint.
For example, i want ARM to send data to PC as a keyboard and mouse.

How can i make multiple endpoint and more complex HID report descriptor.

I use keil 4.54 and rl-arm library.

Thanks for your help.
I found help and manual not clear on this point.

Ah, thanks.
I wasn't aware that usb_config.c includes usb_lib.c

As of override of standard/class request handlers, maybe these routines are callbacks for this purpose.

\Keil\ARM\RV31\INC\usb_lib.c

#if    (USBD_HID_ENABLE)
  ...
#else
  BOOL USBD_ReqGetDescriptor_HID          (U8 **pD, U32 *len) { return (__FALSE); }
  BOOL USBD_EndPoint0_Setup_HID_ReqToIF   (void)              { return (__FALSE); }
  BOOL USBD_EndPoint0_Out_HID_ReqToIF     (void)              { return (__FALSE); }
#endif  /* (USBD_HID_ENABLE) */

To write custom handlers using these callbacks, this SETUP data should be required.

\Keil\ARM\RL\USB\INC\usb_def.h

/* USB Default Control Pipe Setup Packet */
typedef __packed struct _USB_SETUP_PACKET {
  REQUEST_TYPE bmRequestType;           /* bmRequestType */
  U8  bRequest;                         /* bRequest */
  __packed union {
    U16        wValue;                  /* wValue */
    __packed struct {
      U8         wValueL;
      U8         wValueH;
    };
  };
  __packed union {
    U16        wIndex;                  /* wIndex */
    __packed struct {
      U8         wIndexL;
      U8         wIndexH;
    };
  };
  U16          wLength;                 /* wLength */
} USB_SETUP_PACKET;

\Keil\ARM\RL\USB\INC\usbd_core.h

extern USB_SETUP_PACKET USBD_SetupPacket;
