First question asked Welcome!

Hi 

our system is NVIDIA Jetson Xavier NX

 when USB3.0 SSD unplug form Jeston " native USB3 port", OS can show unplug device information.

but when USB3.0 SSD unplug form CYUSB3314-88LTXI USB3.0 Hub,  OS have to wait a long time and then show the unplug  device information.

can I fix the issue?, I want CYUSB3314 have the same behavior as native port.

Hi Dimitry,
As per the USB 3.2 specification, the Hub shall detect a disconnect in 12ms, and then the host will be notified. HX3 was tested against these test cases.

Thanks,

Hi Dimitry,

To debug further in your case, do you have a USB analyzer? If so, is it possible to check if the hub sends the Port disconnect notification to the host as soon as the port is disconnected?

Thanks,
Ajeeth
