Maybe it helps to see some more logs. Hopefully anybody sees what goes wrong.
I thing the OZ6812 is found in a lot of older notebooks, a solution would be good.
Here are the logs of the working CardBus bridge (Texas Instruments PCI1420):

And inserting the same high speed usb cardreader works here:

Pcmcia-card and usb2.0-device work just fine here, it seems to me,
that something goes wrong with the OZ6812.
