So, the combination above is not working for me. I have bought a new DSLR and wanted to transfer pictures at speed from camera to TiBook (which only has USB 1.1 built in). There seems to be plenty of people who have the same card with the TiBook with 10.4.x but not 10.5.x. Basically, the computer doesn't see the card. I slide it in (making sure it's well seated). I plug in a thumb drive or other device, no recognition on either the device or the TiBook that anything has happened. There is some mention about "3rd party drivers" for this card but I've been unable to find anything online so far. Anyone used this card with either TiBook or 10.5.x?
