I ran into a similar problem this week and I think I finally have a solution! In DEVICE MANAGER, under SYSTEM DEVICES - PCI bus, PROPERTIES, IRQ steering, it indicated that the IRQ table was not found.
The "get IRQ table from Protected Mode PCIBIOS 2.1 call was not "checked" and greyed out. By "unchecking" "Use IRQ Steering, I was able to "check" the box beside "... Protected Mode...", the "re-checked" everything. After re-booting, the computer ran properly the "IRQ Steering" was enabled.

: : : Hi,

: : : I'm having problems with a Belkin USB BusPort 2-port PCI card. I'm running on windows 98. I've installed the OPTi 82C861 PCI to USB Open Host Controller with no problems, and it shows up in device manager. However, the USB root hub, when it tries to install (with the correct drivers from windows 98) results in a blue screen with the error message "0028:FF027006 in VXD openhci(01) + 00003C86". In device manager the USB root hub has a yellow exclamation mark over it. Under 'properties' it states a code 11 fault, suggesting a driver problem. I have all the correct files (usb.cat, openhci.sys, uhcd.sys, usb.inf, usbd.sys, usbhub.sys), so why is this happening? Is there a fault in one of my drivers?

: : : Also, in 'IRQ steering' it says 'IRQ Disabled, IRQ table has some errors'. I don't know whether this bears on the situation, as other PCI devices work in the same PCI slot I'm using.

: : : Please help, I've been battling over this one for days...Belkin were no help to me
