Here you posted separate system and debug logs.  Can you get a single 
combined logfile?  It should be a simple matter of changing an entry in 
/etc/syslog.conf.  Set one of the lines to capture kern.*.

You only attached two of those device files, and you didn't say which two
they were.  All I can tell you is that the first one shows a controller in
an error state.

There's one other thing I forgot to mention: When you do this test, after 
plugging in the PC card, rmmod ehci-hcd.  And try plugging the hub into 
each of the ports; maybe some work better than others.

The files you attached were not the same.  Were they for the two different 
device files, both before plugging in the hub?

That doesn't make sense.  Why should a PC Card need an external power
source?

It could well be that the USB/Firewire card is broken.
