Expresscard 54 interface needs work5/18/2010
Sure, it works on occassion, it fits in my Acer Aspire 6930G Express54 slot but it doesn't seem to like to stay in for long. It doesn't ever lock into place. Not sure if it's because of my Acer or the card. I use the card to interface with a Presonus FP10 for music production. It works for a while, then loses connectivity. Again, can't say for sure that it's the Firewire interface.
