It sounds like there is something along the USB stack missing.  Check
your original kernel, and run the command 'lsmod' in a terminal window.
 Look for things like ohci and ohci.  In fact, one better, would be to
run the following command and look for any output at all:

lsmod | grep -i '.hci'

And see what results.  You will need any of those drivers to be built
into your custom kernel (and possibly other ones that the default kernel
has) in order to use USB devices.
