I've certainly used both at the same time, though I've
not got a pcmcia or cardbus adapter -- just using PCI,
addon (OHCI) and mobo (UHCI). You seem to have found
an issue with those pluggable cards.
FWIW I think there's still an open issue with loading
the modules that should get addressed. To wit:
How does one configure a modular kernel so that the
"usbcore" module is automatically loaded only if one
(or both) USB controller drivers will initialize?
I think folk will expect kernel 2.4 to be able to load
the USB subsystem automagically if the system has such
a host controller. And not to do such stuff if there's
no USB hardware there: no 'usbcore' module loaded, no
mounting of usbdevfs, etc.
I don't recall seeing those issues get mentioned before.
