My guess is that this (loaded) usbcore isn't the one that you just
rebuilt.  cd to the 2.4.18 drivers/usb directory and enter
'insmod usbcore.o'.  Well, it just worked for me at least.  :)

Immediately after loading usbcore (without a host controller
driver), /proc/bus/usb/devices is present but empty, and
/proc/bus/usb/drivers contains:
[root@midway usb]# cat /proc/bus/usb/drivers
         usbdevfs
         hub

no, usbcore supplies/produces usbdevfs.

I think that there is just something minor that is being
overlooked here somehow.  Just unload all of the USB
modules, reload them (using insmod filename.o, not modprobe),
and it should work.
