Its a very wired problem that two of my boards connect to WIN10 PC usb3.0 port the system will send reset signal to re-enumerate the device about every few minutes but other boards is fine, it should be a hardware problem but how it happen and what should i notice?

Can you confirm whether the two boards are enumerating as USB 3.0?

Load USB Bulk Source Sink Example firmware and check whether it is coming up as USB3.0 device either in control center and streamer?

What about connecting the two boards to USB 3.0 port of Win 7 PC? Is USB 3.0 enumeration fine?

Yes, its enumerating as USB3.0 and when I use 2.0 cable the problem did appear.

We tried Source Sink and its USB3.0 device

We didn't have WIN7 PC now, will tired it later

Can you capture the USB Trace either using hardware Analyzer and Software analyzer and compare where it goes wrong in the failure boards?

You share the difference between two traces here for the review.

This will help in understanding the issue.

win7 USB2.0和USB3.0都可以传输图像;win10 下USB2.0可以正常传输图像;但是USB3.0需要多次枚举才能识别成功,而且用软件打开视频时,USB3.0设备又会多次重新枚举直到成功识别设备,但是USB3.0然后没有图。USB3.0枚举不成功时,BUSHound显示GET_INFO等,没有IN回数据。

加载EZ-USB FX3 SDK\1.3\firmware\uvc_examples\cyfxuvcinmem_bulk固件后,在WIN10上任然会出现我上面提到的现象,但是多次播放软件点击打开设备后,偶然有一次能成功传输数据,并且播放几秒钟后数据流断了。 除此之外,设备重复枚举时,CY_U3P_USB_EVENT_RESET是一直触发的

我怎么在我自己写的固件镜像文件中,打印USB复位是硬件复位还是软件复位,而且软件复位还分为CPU复位与全器件复位。从寄存器PP_INIT(0xE0017E04)中读取的值一直都是0x00000001

我这里发现与usb的线和pc usb端口有很大的关系,可以尝试下不同的线与端口

Call the CyU3PUsbLPMDisable (); in the CY_U3P_USB_EVENT_CONNECT in CyFxBulkSrcSinkApplnUSBEventCB  in the USB Bulk Source Sink example firmware and check the USB 3.0 Connection with all the combination of PCs and available Cables.

Let us see whether this helps.

Refer API_Guide for the details of CyU3PUsbLPMDisable API.

使用CyU3PUsbLPMDisable ()后,我们的设备可以正常出图,但是具体的原因是什么?或者可以有什么资料可以提供理解这种现象的?

在USB3.0规范中,低功耗模式是一种节能模式,并且在需要的时候可以被唤醒,为什么我的一部分设备会在WIN10下需要禁用这种模式才能正常传输图像数据,而另一部分不需要?对于这种现象,可以提供有一些资料或者思考的方向吗?谢谢

Can you please update to FX3 SDK to the SDK 1.3.4 and test the same samples, which fails to enumerate in USB 3.0?

Here is the link to download the SDK 1.3.4:

使用 Z-tek(ZE646)在Win10系统上,USB3.0和USB2.0传输视频都会传输掉帧,直到帧率为0;我打印的DMA、GPIF、及USBevent都没有发现有异常,如果不用延长线视频传输正常。
