怎么使用HID库通过USB连接PIC18F45 K50到PC

你好！我尝试通过使用HID库通过USB连接PIC18F45 K50到PC。在PC上，我有一个使用Atmel HID库的应用程序，我确信它工作正常。我第一次使用微芯片HID库。所以我做了一个基于HiDuFug示例的项目。这是我的代码：所以我的PC找到了控制器来设置连接。问题是我不能向控制器传送任何东西。HIDRxHandleBusy（U***thdle）总是正确的。还有什么事要我做吗？有特殊的结束符号吗？在PC上，我用1作为结束符号。谢谢！

    Hi! I`m trying to connect PIC18F45K50 to PC through USB using HID library. On the PC I have an app using atmel HID library and I`m sure it`s working correctly. I`m using microchip HID library for a very first time. So I made a project based on hid_custom example.
Here is my code :
//code init
SYSTEM_Initialize(SYSTEM_STATE_USB_START);
   
    USBDeviceInit();
    USBDeviceAttach();
    APP_DeviceCustomHIDInitialize();

//main loop
SYSTEM_Tasks();
APP_DeviceCustomHIDTasks();

//my app device function
void APP_DeviceCustomHIDTasks()
{
    /* If the USB device isn't configured yet, we can't really do anything
     * else since we don't have a host to talk to. So jump back to the
     * top of the while loop. */
    if( USBGetDeviceState() < CONFIGURED_STATE )
    {
        return;
    }

    /* If we are currently suspended, then we need to see if we need to
     * issue a remote wakeup. In either case, we shouldn't process any
     * keyboard commands since we aren't currently communicating to the host
     * thus just continue back to the start of the while loop. */
    if( USBIsDeviceSuspended()== true )
    {
        return;
    }
   
    //Check if we have received an OUT data packet from the host
    if(HIDRxHandleBusy(USBOutHandle) == false)
    {
        //We just received a packet of data from the USB host.
        //Check the first uint8_t of the packet to see what command the host
        //application software wants us to fulfill.
            if(!HIDTxHandleBusy(USBInHandle))
            {

                USBInHandle = HIDTxPacket(CUSTOM_DEVICE_HID_EP, (uint8_t*)&ToSendDataBuffer[0],64);
            }

        //Re-ARM the OUT endpoint, so we can receive the next OUT data packet
        //that the host may try to send us.
        USBOutHandle = HIDRxPacket(CUSTOM_DEVICE_HID_EP, (uint8_t*)&ReceivedDataBuffer[0], 64);
    }
   
   
}
So my PC finds the controller I menage to set connection. The problem is I can`t transmit anything to the controller. HIDRxHandleBusy(USBOutHandle) is always TRUE. Is there anything else I have to do?
Is there a special end symbol? On the PC I`m using 1 as end symbol.
Thanks!
