From Apple: This update adds compatibility for the Que! Fire 16x10x40x drives which use the Teac or Plextor drive mechanism, the VST 8x Bus Powered FireWire CD-RW drives which use the Teac drive mechanism as well as the Logitec 12x10x32 LCW-P1210BF. CD-R drive manufacturers often use several different mechanisms in the same CD-R product. The above drive models and mechanisms are the only new combinations tested by Apple. For more information about identifying the firmware and mechanisms of your CD-R drive, see this Apple Technical Information Library article.
