it looks like the TI TSB12LV26 was used by Adaptec for their firewire card. ref. the link for instructions, and the files are from 2k pro SP4 I don't know what other OSes they will work for
the device I have is enumerated as: Texas Instruments TSB12LV26 OHCI-Lynx IEEE1394 Host Controller
on the card it says:
Adaptec Firewire1394 AFW-4300A LP UNIV HOST ADAPTER 1973600 REV:A 0209 CTB2332-06812 00B0039256
