TUSB8042: Product String registers refrect in iProduct information

Part Number: TUSB8042
Other Parts Discussed in Thread: TUSB8040A,

Dear Team,

My customer has used the TUSB8040A, but it is now NRND. Then, they are considering to change from TUSB8040A to TUSB8042, and they are checking the datasheet of the TUSB8042 now.
There is a question from them regarding the register.

Q1: Is the string set in the following register (Product String registers) of the TUSB8042 reflected in both the "iProduct" information of the USB SuperSpeed hub and USB 2.0 hub?
       Or is it only reflected in the “iProduct” information on one hub, just like Serial number registers?

On the TUSB8040A, the string set by the register was reflected in both the USB SuperSpeed hub and the USB 2.0 hub "iProduct" information.

I look forward to your reply.
Thank you.

Best Regards,

Koshi Ninomiya
