So no usb card has been recognized at this point.

Those are suspicious... but no kernel oops which is good. 

I would do this, reboot the machine with the usb card disconnected. Once
you are logged in su root and type:

tail -f /var/log/messages

(so you see what happens next)
Then plug in the usb card. There should be messages appearing that
recognize the card (from hotplug).
