Unknown Device

[Travis King]

Under the device manager, there's one hardware not installed. It says
'Unknown Device'.
Device type: Other devices
Manufacturer: Unknown
Location: on PCI standard ISA bridge
Any clue by the above information what the 'Unknown device' would be?
Thanks.

Right click on the 'Unknown Device' and choose Properties. Choose the
Details tab. Copy the Device Instance ID and see if you can search the web
for clarification. If you post back here someone here may recognize the
entry. A lot of these unknown devices turn out to be ACPI devices that when
installed are placed under System Devices in Device Manager.

ACPI\PNPB02F\4&A04648&0 is the device instance path.

I beleive that is the game port on a Creative audio card.

Then below where the soundcard is, the game port one is there and is
disabled and not working properly according to the device manager.

Google on "PNPB02F".

I have a fixed a few of the Unknown Devices by clicking on Update
Driver and manually navigating to the location where Vista puts all
our install setup files. Note, you may have to uncheck the box for
"Hide protected system files" in folder view options.

The driver install file are located at something like:
C:\Users\"User Name"\AppData\Local\Temp\{17E362.....}

Dig down into the various {folder} name levels to find a file name
familiar to you. For instance I had trouble with my M-Audio Revolution
5.1 sound card. I located a subfolder with many files with the revo
prefix. Once pointed to that location to "look" for the driver to
update Vista found the correct driver and the unknown driver entry
disappeared.
