Dear Gurus, Several times I've asked the list for help with getting firewire to work on my 2400c/240 without much information. Since this has always been an unusually helpful list, I wonder if the reason for the silence has been that everybody else's firewire worked satisfactorily. I have tried every possible driver combo on 8.6 and 9.1 and firewire works - erratically. Usually my card doesn't come up and the finder quits, or, if I insert on 8.6 before start up, it locks with a dark screen until I remove the firewire card. But sometimes - rarely firewire works fine on both OS's. Ditto - as I finally realized - with my McCally USB card. I may have a "Eureka!" and would like to ask your opinions. PS two different modem cards work fine. Anyway - it occurred to me that maybe, just maybe, my problem is a mechical one that my computer (usually) won't read my firewire or usb cards because my Cardbus was improperly enabled.
