    Hi Kailun:

       TUSB8041A should support item 1,2, and 4.

       Do you have any document about item 3?

    Thanks Brian, 

    The HUB is designed to be compatible with AMD's Firerange and DragonRange platforms.

    May I ask if you has evaluated this HUB for compatibility with AMD?

    Also, regarding the layout routing requirement, it is 8 inches, correct? We need the trace length from the HUB to the USB-A connector to be as long as possible, while ensuring that the USB-A connector meets the electrical specifications for USB (USB3, USB2).

    Hi Kailun:

       Basically,  TI USB3  hub should work with any USB3 host if they passed USB3 compliance test including AMD system.

    correct, we recommend 8 in max from HUB to the USB-A connector to make sure it can pass USB compliance test. if more than 8in, an USB2 redriver or USB3 redriver  may needed.
