[Susanne Schneider]

15:00.1 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller 
(rev 04) (prog-if 10 [OHCI])
        Subsystem: Lenovo Unknown device 20c7
        Flags: bus master, medium devsel, latency 64, IRQ 22
        Memory at f8101000 (32-bit, non-prefetchable) [size=2K]

I almost knew it before checking - shit...
