Just installed a usb 2.0 pci card on xp home sp2 system. Device manager shows
it as a standard enhanced pci to usb host controller. However when I plug my
usb2 external hardisk in, windows can't detect a suitable driver - as usb2.0
drivers are in sp2 why is this happening?

I think the drive is ok because it works in usb1.1 ports ok and uses a
standard usb mass media driver.

The PCI card also seems to work ok with other usb1.1 devices.

I also can't understand why the usb2.0 HD doesn't even work as a usb1.1 on
the usb 2.0 pci card.

I'm betting this is a new external hard drive that you got along with the
USB 2.0 board - right?

Partition and format the hard drive and you will be able to see it in device
manager. If not, then you start trouble shooting.

HDs usually need external power - except some 2.5" or smaller
that are specially designed for low power.

The ext hard disk is my HD in a usb 2.0 enclosure. It is formatted and has a
seperate power supply.
The PCI card is from a separate supplier.

I reiterate -

Device manager shows the pci card as as a standard enhanced pci to usb host
controller. However when I plug my usb2 external hardisk in, windows can't
detect a suitable driver - as usb2.0 drivers are in sp2 why is this happening?

Ok now it is much clearer. What exactly happens when you attach the disk:
nothing, or you see "Found new device" dialog asking for driver?
Do you see the drive in a. Device manager, b. Disk manager ?

XP SP2 contains all required drivers, so normally USB disks should Just Work.

it says found new device and then searches for a driver which it cant find.
It then appears in device manager as an 'unknown device'.

It works fine in a usb 1.1 port but says it can work faster etc etc

May be the card is defective. Also, by chance, does it have any jumpers,
or internal poer connector ?

The card works with other usb devices. There are no jumpers etc.

But are these other devices usb2, or usb 1?
Maybe the defective part is in usb2.
