I have the same issue with ?Other Devices and 2 ?Unknown Devices. I am
thinking that it is both the onboard audio and the PS2 ports as both of those
are unused on my system. I tested both the onboard audio and PS2 ports and
they do not work. I looked through the Device Manager thoroughly and it
appears all of the main hardware installed correctly except for the PS2 ports
and onboard Audio. It's not that big of a concern to me as I have my OEM
drivers CD if I ever need to install the factory drivers, so I just disabled
them so they won't cause any issues. It would be nice to know which one is
which though, meaning is the top ?unknown device the PS2 ports or Audio? I
really don't recommend forcing drivers on an ?unknown device entry in the
device manager as this causes major system instability even if it is the
correct device that you install the drivers for. But if you are really picky
about these entries in your device manager, here are some troubleshooting
tips. Reboot and when the computer is starting up press the F8 key, it helps
to keep tapping it, and from the Startup menu choose Safe Mode. In Safe Mode
have a look in the Device Manager to see if any more information about the
devices are revealed. If not, restart into Windows Normal Startup and go to
the Device Manager and right click on the entries and uninstall them. Load
all device drivers for the devices you suspect are causing the issue from the
Drivers/Utilities CD that came with your motherboard/computer. It can help to
click on View and then select Show Hidden Devices, which will reveal the
non-plug and play drivers, so you can look to see if the drivers loaded
correctly. Personally, if Vista didn't recognize a few of my ports/devices
and I don't use them anyway, I would just disable the unknown devices and
forget about it.
