Hi I'm using an old PIII PC which doesn't have native USB 2 support . So I bought a PCI USB 2 card , the onboard controller chip is ALi . I could connect eeverything at USB2 speed but not HD3 , it always shows "Not recognized device" . If someone here also uses PCI USB2 card and successfully connected , could you please check your controller chip name . I saw on the market where I live they have 3 types : ALi chip , Via VT 6212L , and NEC 0720100AGM . Also it is strange that both PCI USB 1.0 and PCI USB 2.0 use VIA VT 6212L , the only difference is that USB 1 has 2 ports , USB 2 has 4 ports . Why do they do that ? Thanks for any info , I need to buy the new PCI USB urgently , it's too slow to trasnfer with USB1 port on my mainboard.
