That's more or less where I'm coming from. Init the core (including
HCDs), then the rest can use PNP.

If I "modprobe usb-ohci" (ditto with UHCI HCDs) "usbcore" is
automatically loaded, by virtue of those dependencies.
I _think_ that should let the PCMCIA subsystem handle all
that it needs to handle. It sees a new USB card, modprobes
its HCD (usb-ohci probably), and then USB is operational
because (a) usbcore got modprobed due to dependencies,
(b) a 'usbd' got started (perhaps it's using KUSBD, or a
post-install started a user-mode USBD), often even (c) the
usbdevfs got mounted as a post-install too.
