/lib/modules/linux-X is set up so that modprobe and udev know some
more info about the modules (specifically for modprobe
/lib/modules/linux-X/modules.dep).
So without that set up insmod is the only tool that will work. So if
you go to the directory where the .ko file is and do 'insmod
usbserial' what do you get?
Also when using /etc/modules you just list the module names there is
no need to add a modprobe before the name, but again that depends on
the modules_install.
To do kernel development I would suggest getting a proper NFS setup
with a tftpboot for the kernel.

So I think that means you need to select some other option under
usbserial did you choose "generic serial driver"? If you want to load
the module manually you need to

Then run a 'depmod' command on the linuxstamp to fix up the paths, and
it should load automatically through udev when you plug in the device.

The root nfs is just a test environment until you get things working.

Where ftdi_sio is another kernel module. There's a ton of these under
usb serial converters; you can always choose all of them and let udev
sort it out.
Also unless you don't have udev installed you'll want and remove the
nodes you made yourself.

First, make sure that the use-to-serial functionality works correctly
as embedded. then you will investigate the problem.

It's very dangerous to edit the .config file directly. I would use
xconfig or menuconfig to do that ('make ARCH=arm
CROSS_COMPILE=arm-linux- xconfig'). I think this will be much clearer
once you see the configuration from xconfig, it's a fairly nice
interface.
