TPS2546: USB ground connection for ESD/Surge test

Part Number: TPS2546

Hi,

My customer used our TPS2546 for USB BC1.2 charging. While they have questions related the USB ground connection for ESD/surge test. How to connect the USB signal ground to the case ground of equipment for better ESD/surge test?

 

Can you share any experience of that?

Many thanks.
