TPS65982: Detection of USB2.0 or USB 3.0

Part Number: TPS65982
Other Parts Discussed in Thread: HD3SS460,

Hi Team,

My customer would like to know which data rate connection(USB2.0 or USB3.0) is established on USB line. And they hope TPS65982 or HD3SS460 has any indicator functions(like status register).

 Does TPS65982 have such function to distinguish established standard on USB line?

I think it might be impassible because the established connection doesn't depends on physical layer but link layer. But let me double check just in case.  

Regards,

Takashi Onawa

    Hi Onawa-san,

    We do not offer such functionality on the TPS65982.
    However, there are certain applications that can be installed on your computer such as USB Tree Viewer that can be used to distinguish the established standard on the USB lines.

    Thank you,
    Eric

    Eric-san,

    Thanks for your quick response.
    Yes, I understand USB host can get the list of all connected slave information but their application just contains USB Hub.
    I will explain them that there are no function in TPS65982 to know established data rate.
