Linux/AM5718: Got usb hub port error, EMI, re-enabling

Hi Feng Liu,

The DM3730 advisory 2.1 is not applicable for AM5718 but there are several USB related advisories.
I checked USB camera connection but there is no issue in general. Therefore I suspect there is something specific with environment. Could you attach the whole 'dmesg' command output after observing the issue. Does the issue appears every time or sometimes?
Are check with other USB camera?

Hello Tsvetolin,

Thank you somuch for your verification.

An UVC camera may be working well for a long time,and the error occurs while lightly hammering USB connector on AM5718 board. Google results show somebody met the same issue on Raspberry board too. Can you share the links on USB advisories of AM5718.

The debugging message as below,
