    Sorry, I don't understand your questions.
    Your DSP requires to have xHCI driver support, if your operating system is windows 7 you can use the driver available at the link below, if your OS is windows 8 or above, the xHCI driver is supported by microsoft.
    Are you able to communicate with the TUSB7340 via PCIe ?
    Can you get a PCI register dump of the TUSB7340?
    Regards

    Can you share your schematics?
    Are the USB devices enumerated by the host?
    Can you tell if the USB downstream devices are being enumerated?
    Have you tried different USB devices?
    Can you get a USB protocol trace?
    Have you tried with the newest kernel?
    The information you provided is not enough to know what could be wrong.

    Hi. Team

    I can share schematics.
    Please share your e-mail address.

    USB2.0 is not currently a problem.
    From 24Mhz to 48Mhz Crystal USB2.0 After replacing the crystal is not a problem.
    But USB3.0 is still not recognized.

    Linux kernel 4.1.35 were used.

    What should I check for USB3.0 recognized?

    thanks,

    Best Regards
