  • Hi Chris,

    DM646x datasheet states that only USB2.0 is supported.

    See also below e2e post:

    Pavel,

    USB3.0 is backward compatible to USB2.0. Customer can work ok with some USB3.0 U disk on DM6467. But with certain USB3.0 U disk, after writing to U disk some time, there will be error I showed in the first post.

    Do you have any idea on the problem with the error info?

    Thanks,

    Chris
