Angstrom-USB problem

I've install the angstrom demo image on beagleboard, but the usb
devices not work.
I have a usb hub that work properly on windows and ubuntu.
I attached the serial cable from beagle to windows.
When I connect the usb hub, nothink happens. I think that the angstron
would send somethink to serial output but it didn't. I tried to
attache the keyboard directly but the beagle don't notifier by serial.

So i guess that it must be the usb module.
I try to load the module g_zero.ko but its returned to me the
following message;

root@beagleboard:/lib/modules/2.6.29-omap1/kernel/drivers/usb/gadget#
modprobe g_zero.ko
FATAL: Module g_zero.ko not found

When i use the ls.

root@beagleboard:/lib/modules/2.6.29-omap1/kernel/drivers/usb/gadget#
ls
g_cdc.ko g_file_storage.ko g_printer.ko gadgetfs.ko
g_ether.ko g_midi.ko g_serial.ko

Maybe start syslogd and watch /var/log/messages for activity on the
USB host interface.

I think you have the syntax for modprobe wrong. Remove the .ko part
and try again.
eg.

modprobe g_zero
