Hi all ..

I am facing problem in compiling kernel for USB Support. while selecting the
option i have selected the USB host configuration but while compiling i am
getting the following error :-

drivers/built-in.o(.text+0x7a1f8): In function `usb_register':
drivers/usb/core/usb.c:174: undefined reference to `usbfs_update_special'

This is for PPC8272-ads board using Montavista Linux. Can any body suggest
me that what else configuration is required (which i had missed ) is giving
this error ????

Looking forward for your help
