I put a second USB card in pci slot 2 but try as i may with drivers cd supplied it fails to operate. There is power to the USB sockets as any USB item i attach powers up but the computer does not recognise it. Device manager shows no problems with USB devices. Existing USB card in slot 1 works fine. Any Ideas ?
USB Card is a Mercury with Via chip. I tried uninstalling drivers and it also uninstalled the drivers for the working USB card. Reinstalling drivers for USB Card Two merely enabled USB card i again. If you can follow that. OS is XP SP2
I have tried putting USB card in different slots (I have 2 spare) What now happens on boot up is that I get a message saying "New hardware found -Enhanced USB Controller" then a second message saying "searching for drivers" and at this point computer freezes. I have tried uninstalling all USB drivers but computer still freezes at the same point. I have had to remove the card to enable the computer to boot.
