USB driver problems

[Guest]

I seem to have run into a common problem with usb ports, but can't find the
solution.

I'm running Win2K on a PC which has its own PCI to USB host controller on
the motherboard. The USB ports on this controller work fine. I added a PCI
card to provide another set of USB ports. This is has a different controller
chip. The card and its ports are recognised: no problems visible in Device
Manager/Hardware.

For a while. the new ports worked ok.

But - if I plug now any USB device into the new card, it is either not
recognised at all (e.g. for a USB flash memory) or an error message appears
(e.g. an external USB disk drive) that no function driver was specified + a
yellow flag in Device Manager/Hardware against the USB device.

The same USB devices are recognised correctly on the other controller.

I presume that the problem is that Win2K is loading / has loaded the wrong
driver at some stage.

I've tried uninstalling/reinstalling the PCI card and the USB devices to no
avail. How do I track down the problem and correct it? Any ideas welcome...
short of doing a complete reinstall!

Thanks

looks like the device has failed...
since it originally worked it does not look like a driver problem

Try installing the Controller into a different PCI Slot and see if that
works. USB is a great technology but some times it can cause some headaches.
