I have built the the 2.4.12 kernel with CONFIG_HOTPLUG set and the usb stuff
all compiled as modules.
depmod -e shows that usbcore.o has an unresolved symbol (which of course
fails when the module tries to load) of hot_plug path.
Looking through the code I can see that this gets defined in kmod.c - and
there is an entry in System.map (I don't know each line means but
hotplug_path is there). I can also see the kmod.h (included by usb.c which
eventually gets built into usbcore) defines it as an external reference.
What I have been unable to figure out is why depmod doesn't link usbcore.o to
it.

I need the output from
nm -A `/sbin/modprobe -l` | grep hotplug_path
grep hotplug_path /proc/ksyms System.map

Thanks - solved. I've read the FAQ several times but not groked that bit.
