I am trying to add usb ports to a Via mobo with an intel PII 350mz chip.
Have added both an opti board and usb riser.
Device manager now shows:-
Opti 82C861 PCI to USB Open host controller (working ok)
and Via VT83c572/82c586 pci to USB universal host controller (working ok)
and USB Root Hub x2
but nothing happens when I plug in any kind of USB device (HP845 printer/ card reader /hp scanner)
Already installed 4in1 drivers and filter patch
Opti board works fine when plug into AMD1.2 K7 mobo
Please Help!!!

What operating system and are you running the driver disk first then plugging the usb cable into the pc when it says searching for device?

Have you enabled USB in CMOS

Go with woodchip boot into the BIOS/CMOS normally Delete when booting and check USB is Enabled.

Ok then try Removing the Via VT83c572/82c586 pci to USB universal host controller and rebooting. Then try the attaching a usb device again

The USB on the Board, may have blown the built in fuse which cannot be replaced. But a USB PCI card will work round that Prob

PS go to device manager and remove all USB you can find and reboot your comp

Have removed opticard and via from devicemanager and rebooted, win98 found new hardware via and opti and reinstalled drivers found new hardware and reinstalled on;ly one usb root hub for opticard but still will not see anything plugged into it.

Card reader drivers installed prior to reboot.
card reader not found on reboots if left in or put in after boot.

Hair now getting very thin any more suggestions?

Thanks for the help so far
