Hi everyone, I have this computer:

MB: Abit VH6T
CPU: Celeron 1.3Ghz
RAM: 512 MB
OS: Win98SE with NUSB patch.
GPU: Nvidia FX 5200 Ultra and Diamond Monster 3D II 8Mb

I've installed a NEC USB 2.0 PCI card and now I have this issue: I can't use the Voodoo and the USB ports in the same time.

If I plug an usb device first then the voodoo card doesn't work (donut demo crashes, often the whole Windows).
Vice versa If I launch donut demo right after boot it will work, but then if I plug anything in the usb ports the PC will just hang forcing an hard reboot.

With onboard USB 1.0 ports everything works always.

I guess I do have some resources conflict? But there are no warnings in the device manager.

What i tried so far:

  1. Change PCI slot of the USB card
  2. Remove other PCI cards (a creative audiopci and a realtek ethernet card)
  3. Change Voodoo drivers (right now I'm using the FastVoodoo 4.0 GE)
  4. Reinstall fresh win98se

What else can i try? I'm currently reinstalling 98se for the third time this day in the meantime!

This may be an issue with the southbridge. VIA had some problems back then that were mostly worked around by driver and BIOS updates. Try the latest BIOS and see wether different chipset drivers make a difference.

I had no end of problems and performance impacts when using an NEC chipset USB 2.0 card with a VIA MVP3 board.

Switching out to a VIA chipset based USB 2.0 card resolved everything.

Indeed I have solved with an ALI USB 2.0 card but I may still upgrade the BIOS because I still have occasional system hiccups or freezes until I remove/plug back any of the PCI cards.

USB cards require like 3 IRQs which easily leads to IRQ conflict when all devices are in use simultaneously due to PCI IRQ sharing. One way to work around it may be to free IRQs by disabling the built-in USB controller, serial, parallel ports in BIOS. Then Voodoo 2 can get assigned its own IRQ.

It may also be Win9x causing the problems. Sometimes 2K/XP work fine on a configuration that blows up 9x. I shudder at the thought of whether it could be ACPI, PCI PNP, or VXDs causing that. I usually just disable USB 2.0 with it.
