I just wanted to post that the cardbus is detected out of the box.
Using Mint 3.1? XFCE Cassandra.
This card has 2 usb 2.0 ports, 1 6-pin firewire and 1 4-pin firewire.
The usb ports easily connected a 1gb pny usb2.0 flashdrive and a Compaq optical usb mouse. No problems.
I haven't my Presonus Firepod with me at work, but last night I got no connection with jackd -d freebob and wondered if the card was even detected.
Now I believe the issue is a freebob/udev thing.
