Hi ,

We are trying to add USB support in one of our MPC8313 Based card running in Linux platform and USB clock is provided from a 48Mhz crystal in the card,

Following are the steps we followed to do the same ,

 1.In Kernel config we added USB host support and Mass storage support

 2.Device tree we added USB node like below,

 usb@23000 {
           device_type = "usb";
           compatible = "fsl-usb2-dr";
           reg = <23000 1000>;
           #address-cells = <1>;
           #size-cells = <0>;
           interrupt-parent = < &ipic >;
           interrupts = <26 8>;
           phy_type = "utmi_wide";

But now when we boot the card we are getting the following error & board is hanging at this point ,

vfsl-ehci fsl-ehci.0: Freescale On-Chip EHCI Host Controller
fsl-ehci fsl-ehci.0: new USB bus registered, assigned bus number 1 "

if someone have some idea,could you please help to solve this issue

Thanks in Advance
