Hello Dave,
I tried to pull the changes from 2.4.27-rc. Hardly there were couple of changes with respect to the ehci host. (one in ehci-hcd.c and another in ehci-sched.c).
Thats also didn't help me.
I am not able to apply the complete patch because it might ruin my platform specific changes.
Please suggest me what else I can try or how can I debug.
Will CATC Help me in debugging this. I have one with me.
Can EHCI work without the IRQ working fine (as suggested in the code that it can work with the watchdog timer function)?
I am putting the transcript of the error messages once again here, just in case.
warm regards, Nazim

Further debugging into the code revealed that the handshake() function is returning this error. (in ehci-hcd.c). The only reason left now is that the done bit is not getting set in the controller.
I've certainly had success reports using EHCI with big-endian MIPS with 2.4.26, but since you're using little-endian MIPS (SPIM?) it's not going to be a byteswap problem. Does 2.4.27-rc work better? Or 2.5.7? A few patches have gone in that might affect you.
