CYUSB3KIT-003开发板https://community.cypress.com/t5/USB-Superspeed-Peripherals/FX3-slave-FIFO-to-UVC/m-p/44377这个帖子中cypree专家给的附件程序时debug信息出现"SUSPEND encountered...",发现程序运行到了CyFxUVCApplnUSBEventCB()的
...
case CY_U3P_USB_EVENT_SUSPEND:
CyU3PDebugPrint (4, "SUSPEND encountered...\r\n");
CyU3PGpifDisable (CyTrue);
gpif_initialized = 0;
streamingStarted = CyFalse;
CyFxUVCApplnAbortHandler ();
break;
...
这个位置,是表示USB停止了么,什么原因?谢谢

这个USB event是FX3处理USB host发送的命令产生的,那你这里一个摄像头枚举了没有串流,就自动进入suspend

这个。不影响编译。
