Hi,


Sorry for the inconvenience. I might have overlooked your latest response.


Thanks for your clarification that you are targeting USB4. As I understand it from the S10 L/H-Tile user guide, seems like there is no specific information about USB4 protocol.

Please let me know if there is any concern. Thank you.



Best regards,
