Hi, do you know if two TUSB4041 connected with a 5m USB cable can comply 1kV Signalburst Test with Criteria B ?

(CritB: after the burst disturbance the connection should be reconnected without user action)

Hi Ueli,

We don't have any collateral / docs specific to the USB hubs on burst testing. I did see a few documents from the team that does protection devices that may be useful. Does the current design implement TI protection devices?
