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。

    Hi

    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…

And also we do not support pcie driver in recent release. Sorry for the convenience. If you want to read and write data from the USB disk, can you choose the USB interface?
