Okay. It appears I haven't been totally clear in my messages.
You are correct that I built usb-ohci as a module in the past.
Building usb-ohci in the present as a modules also works
(the OHCI bridge gets detected).
I would like the option of building usb-ohci into the kernel
and have some usermode process scan for hubs and USB devices
after the Yenta and PCMCIA drivers are loaded. Is this what
it would take to get the in-kernel usb-ohci driver to perceive
the presence of my Belkin cardbus USB hub adapter?
Note that I am not building the Yenta drive as a module.
Perhaps if I tweaked my initialization scripts I could get
the Yenta driver to initialize before the USB hubs get
scanned. Do you know if this is possible? Perhaps that
portion of the initialization sequence is hardcoded in the
kernel.
Thanks,
Miles
