usb devices do not work correctly

I removed an old USB device which plugged into 9 small pins on the motherboard. I instaslled a PCI card with 4 USB slots. On reboot the drivers are asked for (uhcd.sys, usbhub.sys, usbd.sys and openhci.sys). The first three load OK but when I load openhci.sys the PC just hangs.

could you not have left it, and just added the PCI card?

Where are you getting these drivers from?

Which version of Windows are you using?

I tried leaving the old device in - no difference. I'm using windows 98. I extracted the drivers from the Windows Installation Disc. The Microsoft Knowledge base article (number 299264 -use search "uhcd.sys") deals with this problem but doen't mention "openhci.sys". If I don't load "openhci.sys" the PC works OK but no USB devices are recognised.

If your new usb card is usb2 then I rather think usb2 is only supported by windows xp with service pack 1 installed

Someone else may know if the necessary files, which are included in the service pack, can be obtained for earlier windows o/s
