My physical drive has two partitions and both use the identical version
of WinXP Pro. However, one of the drives keeps telling me that I have
new hardware (USB) but it cannot find the driver. So, for now, I
disabled it. But I would really like to know what this device is. Is
there a way to find out?

(Contrary to the article's "Apply's to" section, the information is
legitimate for XP, as well.)

But my unidentified device is USB.

Open Device Manager, and on Device Manager's menu click View, then click
"Devices by connection". Expand the trees. Usually USB's are under the PCI
Bus, and are therefore "PCI devices".

When a device driver for a device is not available, Device Manager displays
the device as Unknown Device, and places it in the Other devices branch.
This is very common with Universal Serial Bus (USB) and Institute of
Electrical and Electronics Engineering (IEEE) 1394 composite devices. Also,
a status of Error Code 1 or Error Code 10 may be displayed when you view the
properties of the device in Device Manager.

NOTE: Most USB and IEEE 1394 devices are designed to function properly
without additional device drivers, because they are configured by the
drivers included with Windows for these bus types. However, an additional
device driver is needed if the device does not fit the defined and supplied
Windows class drivers. If the bus cannot identify the device, it interprets
the device as a composite device and then reports it as such in Device
Manager.

Here's another way to go at it:

1.Open Device Manager.

2.Open the properties for the device in question. Click the Details tab.
Make sure that "Device Instance Id" is selected in the drop-down menu on this
tab.

3.You will see a string like this one:

PCI\VEN_8086&DEV_2658&SUBSYS....

In this example, 8086 (after VEN_) is the Vendor ID and 2658 (after &DEV_)
is the Device ID.

4.Go to http://pcidatabase.com and type the appropriate numbers/letters into
Vendor Search and Device Search, using the Vendor ID and Device ID that you
just found. In the example above, it was "USB UHCI Controller #1", made by
the "Intel Corporation".

5.Refer to vendor's web site for appropriate drivers for device.

Hope this helps.
