ADSP589 PCIe interface problem

we have a ADSP589-EZ-kit   and  i connect  a pcie-to-usb  converter with pci interface on ez-kit.  Then I connected a u-disk to the usb interface of converter ,I can only read data from the USB flash disk, but I can't write data to it.The adapter chip is pd720202 of Renesas。

    I think if you want to use the converter, there should be a driver to support this, unfortunately we do not  support the pcie-to-usb converter yet. And also we do not support pcie driver…
