CSR8670 在source_usb.c里有一个问题，有谁能告诉我

void usb_send_hid_answer(void)
{
    if (theSource->ps_config->usb_config.usb_hid_keyboard_interface)
    {
      /* send ALT+PGUP over USB */
       UsbDeviceClassSendEvent(USB_DEVICE_CLASS_EVENT_HID_KEYBOARD_ALT_PGUP);
    }
}
USB_DEVICE_CLASS_EVENT_HID_KEYBOARD_ALT_PGUP找不到HID相关描述
哪个大神，能告诉我一下，谢谢啦！

楼上，你好！这个表放在哪个文件下的，我没有找到

源代码的source_usb.c里HID描述，里面只有(Consumer Devices)的，哪个大神，能不能给一份里面有(Telephony Devices)的描述？
