Can you share the exact line of the error you are talking about?

I inserted a USB 3.0 camera into the USB 3-1 port, and I didn’t unplug it, it showed disconnection, and then it was detected again

Hi,

Do you only see such disconnection with this kind of device? Or even other SS device will hit this issue?

It’s related to the length of our cable. When I replaced the shorter cable, the problem didn’t appear.

Please check the tuning guide here. You shall let it the pass EYE diagram test.
