error:hub 2-0:1.0: over-current change on port 1

Hi,

I'm using TI dm8168 board and the EZSDK version is 5.05, and I have met the above error:hub 2-0:1.0: over-current change on port 1、.

In the "DM816x EZ Software Developers Guide" say:

"This error message will be seen if the daughter board is not connected with the J5Eco EVM. In this absence of
daughter board the USB1 port is hanging this produces the above error. In case you do not want to use
daughter card you can disable the USB1 port by applying the patch provided in PSP release notes documents."

But I have not found the patch in PSP release notes document. Can you help me found the patch? 

Thanks.

    Thanks for your replay. Yes, it is the document  ti-ezsdk_dm816x-evm_5_05_02_00/docs/DM816x_EZ_Software_Developers_Guide.pdf , but I have found the issue .

    In my board , the voltage provide to USB is not stable , so after I fix the voltage issue , the error is not occured.

    I am glad you solved your issue. Just to add that I can not find the above information regarding USB1 port in the DM816x_EZ_Software_Developers_Guide.pdf

    Hi Pavel,

    I hope that this is the right forum to post this question on.

    I get the following error messages all the time on my Custom TI8168 board using the ezLinux SDK. We do not use the USB interfaces at all and I have disabled them in the kernel but still see the messages all the time on the terminal side so the system is unusable...

    hub 1-0:1.0: over-current change on port 1
    hub 2-0:1.0: over-current change on port 1
    hub 1-0:1.0: over-current change on port 1
    hub 2-0:1.0: over-current change on port 1
    hub 1-0:1.0: over-current change on port 1
    hub 2-0:1.0: over-current change on port 1
    hub 1-0:1.0: over-current change on port 1
    hub 2-0:1.0: over-current change on port 1
    hub 1-0:1.0: over-current change on port 1

    Please assist.
