usb-console in u-boot

[arjun rath]

Hi,

This is arjun..at present m working on usb console
in u-boot for smdk2440 arm...I taken the code from openmoko u-boot,but
the openmoko code doesnt work at all...can u give some brief idea
regarding this..

I am trying with u-boot-1.1.6 and added support for s3c2440_udc.c inside
driver directory from openmoko u-boot and all the dependencies for the
udc driver..but with the code the  device is not able to enumerate.When
i tried with debug messages....the control is not going to Endpoint Zero
Handler Routine..and its not generating the interrupt ,so i think tat is
the reason its not able to enumerate and in dmesg its showing "usb 3-2:
device descriptor read/64, error -71"...

So is there anything missing or any other dependencies for to get a ACM0
device in host...any suggestion will be greatful...
