Hello CS,

When the USB 3.0 device is removed do you see that it is reported as disconnected by the USB host? What operating system are you using? What type of USB 3.0 connector is being used?

Regards,

Hi CS,

If the hub is powered up with no USB 3.0 devices connected and one is attached, does it show up? Do you have any debug output from the USB host controller?

Regards,
