Rick,
    Very interesting. I have never seen these files. Thanks.

    There seems to be only one line for the OHCI devices. I'm sort of 
assuming that having all f's is an indictation that this driver should 
load for all OHCI devices?

    Would I change the vendor/device values on the ohci1394 line to 
match the TI chip and then possibly nothing would get loaded for the 
Creative Labs? Looks like I need to reverse map the TI/TSB12LV23 
numbers, as well as the ADS Subsystem values to get what I'd put in this 
file.

    Sound basically correct?

Thanks,
Mark
