USB rettentő lassú

Sziasztok,

van egy régi IBM Thinkpad R31-es laptopom, amin csak 1 db USB1-es port van gyárilag. Nemrég vettem egy noname 4 portos USB2-es PCMCIA kártyát, mondván hogy majd arra fogom a külső vinyómat rádugni. XP alatt a kártya normál sebességgel hajtja meg a külső vinyót (írás/olvasás kb. 16000KB/sec), viszont a laptop 8.04-es ubuntuja alatt a dög csak USB1-es sebességet produkál (kb. 700-800 KB/sec). Itt az info ami összejött a kártyáról:

Van valami ötletetek, hogy miként lehetne rávenni a cuccost USB2 sebesség használatára?
