a little more info. after poking around i find that usb-core is not
loading. i try to run insmod usb-core and i get:

insmod: can't read 'usb-core': No such file or directory

i try:

insmod kmod-usb-core and i get the same error.

if i do lsmod i see 
usb_storage            86408  0 

but no core module. 

is the usb_storage module the only module needed for this?

thanks for any help on this issue.
