help with USB on mpc8313e

Hi,
I am trying to use the mpc8313e internal usb phy with internal oscillator frequency of  24 Mz. in host mode on a custom board.
Whenever I plugin any low/fast speed device the device gets detected but then always get an error
"cannot read descriptor 64  error 71".Also I get address error after that .

Can somebody point me what this error can be related to ?Can it be a problem with ehci drivers or some configuration. (I get a valid clock bit set in the status register).

Also can someone point me how I include support for mmc on spi. I am using kernel 2.6.20 that comes along with mpc8313e bsp.

Any pointers are highly appreciable.

Thanks in advance
Regards

This reminds me: http://patchwork.ozlabs.org/linuxppc/patch?id=17782
Was getting exactly same symptoms.

Try similar changes, should help.

Thanks Anton,
With the kernel version 2.6.20 I am using Majority of this changes are hard code values in mpc8313.c
I did already changed this value for my custom board file.
But I am getting  the error irrespectively.

Is the relatonship description between USB DR clk and other as mentioned in your thread  is documented in the manual . I could not find it atleast in mpc8313e user manual.
