In my experience, the cheaper cards will do this the most, along with cards that
may have an issue with the BIOS or are just plain defective. Bad/incompatible drivers
also will do it.. Most often, I will try another brand card. The worst are the
generic/house brand cards, while the best cards I have had good luck with are the
Adaptec cards.. It's not only a symptom that happens in Win 9X but it can happen
in NT/W2K/XP also for the same reasons.
Ghost entries are normal even on a stable operating system. I've never seen a real
good explanation as to why for every system I've seen it on. I have an old asus
board that runs W2K and Win 9X that has 4 or 5 entries on some items and it never
crashes on W2K and rarely on Win 98SE so don't know for sure why. It's reported
to be an issue with the PNP system and incorrectly written code by driver and software
vendors. It is an issue however when it comes to troubleshooting Win 9X systems.
So that's where I always start on Win 9X, is by deleting duplicate, or sometimes
all devices and let Windows redetect them again.. Have you tried disabling the onboard
USB (in the BIOS and Windows if it shows up) and see what happens with the add-on
card?
