yes you are right....i compiled my kernel with "kernel in nutshell" only....i runned "make modules_install" while i build the kernel....i already told that i disabled the entire usb support when i build the kernel.....so help me what to do....still getting error after i use "depmod -a"...see below...

I think you lack some knowledge on kernel configuration, compilation
and installation. Therefore, I would recommend to read Linux Kernel in
a Nutshell, written by Greg KH. Printed copies are available from every
good on-line book store. Electronic copies are also freely available
online, at http://www.kroah.com/lkn/.
If you're doing native compilation (i.e compile a kernel for your
workstation), then after the compilation, run:
make modules_install
This will automatically install all kernel modules
in /lib/modules/<kernel-version>/, and run "depmod -a" which
will
create a few text files needed by modprobe to get the dependency
resolution system to work properly.
If when running "modprobe foo", module foo is not found, it's
because
the module hasn't been installed in /lib/modules/<kernel-version>/.
But again, please read Linux Kernel in a Nutshell, or at least the
relevant parts of it, to at least get a basic understanding of what's
going on.
Sincerly,
Thomas
