Device Manager is not Installing Drivers RRS feed

  • Question

  • I have a strange problem on a user's laptop that has me completely stumped. It started off when she got a new external hard drive. When the external drive was plugged in it would not show up in Windows Explorer. When I looked at device manager the device was there as an "Unknown device" with a yellow ? icon. I've tested the external drive on another system and it works fine and when I plugged a USB flash drive into the laptop it worked but when I looked in Device Manager there was still an "Unknow Device" listed. I manually updated the drivers in Device Manager and windows installed it as a "Generic Volume".

    So all this leads to the real problem. Any time a new hardware device is added to the system (or even if an existing device is uninstalled) and the new device is detected by Windows -- either by reboot, Plug-and-Play or by forcing device manager to scan for hardware changes -- these devices are detected and listed under Unknown devices and the driver installation dialog is never launched.

    If I then select the devices individually and choose "Update drivers" then the drivers will install as expected. What could be causing this particular system not to automatically attempt to install drivers for new hardware when detected?

    I've tried running sfc /scannow to repair any corrupted system files and checked that the Plug and Play service is running. No errors or messsages are logged in the event logs when the hardware is detected indicating a failure to start the install? Any ideas? I'm hoping to find a fix without reinstalling from scratch.

    Thanks in advance.


    Thanks...Ray

  • Ray, I'm not entirely sure if these kind of non-action errors are even logged in the XP Event Viewer, but can you check eventvwr by running it from the Start menu and then Run?

    Look under Applications and System. See if there are any errors or warnings hinting and referencing device driver installations and post their descriptions here in this thread.

  • use microsoft fixit tool.. it should fix the driver issue.. Also you can try plugging the usb device to the high speed USB ports.

  • I did check the logs and there were no events related to drivers.

  • I tried to use the Fixit tool but the only one I could find referring to this issue was for Windows Vista and wouldn't run on the XP machine. If you have a link to an XP fixit for this issue, please post.
