bug修改

        USB_SendData(UsbOutBuffer,OutNumber);   //发送数据缓冲区，长度（接收数据原样返回, 用于测试）
		printf("功德+1: %u 次\r\n ",(unsigned int)(GD1));
                GD1 ++;
         usb_OUT_done();

改为 解决串口输出延迟一次按键计数的bug

        USB_SendData(UsbOutBuffer,OutNumber);   //发送数据缓冲区，长度（接收数据原样返回, 用于测试）
		GD1 ++;
		printf("功德+1: %u 次\r\n ",(unsigned int)(GD1));
        usb_OUT_done();
