You mean the OHCI host controller?

"cardbus USB hub adapter" is confusing to me also.
Is this a cardbus-to-USB (OHCI host controller) Type II PC Card?
What's the word "hub" doing here? Are you just referring
to the "virtual root hub"?

I'm not sure that this can be made to work in the released
kernel. You may be able to patch a kernel to make it work.
I'm just guessing, but I don't think this is an issue with
the ordering of some init scripts. I think it's ordering
within linux/init/main.c, which has the following init
order (with several omissions here) [// comments are mine]:
pci_init(); // needed early
usb_init(); // after PCI and before PCMCIA;
// before do_initcalls() so that
// USB initcalls work
do_initcalls();
...
init_pcmcia_ds(); /* Do this last */ // why last?
I don't know why init_pcmcia_ds() should be last.
For your config & kernel to work the way that you want it
to (in kernel, not as modules), I would try moving
init_pcmcia_ds() above usb_init().
Alternatively, if you aren't using any USB modules,
you could try moving usb_init() to after init_pcmcia_ds().
