winXP won't boot with USB 2.0 card

[zheniok]

Hey, Does anybody know what can be causing WinXP not to boot when I plug Adaptec's USB 2.0 PCI adapter? My motherboard is ASUS A7V266-E with AMD XP 1500+. I flashed the bios to Rev. 1005, but it didn't fix it. The USB card is definitely good, since I tried it on a different machine and it worked fine. I also tried plugging it into a different slot, but no result there either. However, when the card is out, everything works just fine.

Please help.

Thank you.

Thanks zheniok...I know I won't get Adaptec's version...but did you download WinXP USB 2.0 drivers?

hmm, have you tried disabling your m/board own usb in bios before installing the usb card?

btw welcome to the forums!

thank you for responding,
Unfortunately it was none of those things. I tried disabling on-board bios, on-board sound, taking out all the cards out, except for video - nothing. At first I blamed Adaptec, but then I went ahead and bought SIIG's card - same thing. Works fine on one computer, but on this one XP freezes at boot up every time I insert the card.... What else can it be? Oh, also I tried downloading all the latest drivers, including MSFT's patch for USB 2.0.

Hmm you've tried everything I can think of.

Have you been able to boot up XP into safe mode?

Am running XP Pro, and have a combo USB 2.0/Firewire PCI card (OrangeMicro) installed in a PCI slot that was paired with the onboard USB1 ports. I disabled the on board ports in BIOS and everything works . . . both Firewire and USB 2.

So, try putting your USB 2 card in a different PCI slot. Asus boards are usually slot-paired for sharing, and some things share better than others. (Slot one shares with AGP and is almost always a loser so I never use it.)
