USB not working

  1. Hi All,

    I've an issue with a Dell XPS 15 running a 64 bit Win 7 with fully updated drivers.

    Whenever I insert a usb to the usb 3.0 port (it doesn't have anything else), it finds the drivers for it and installs them successfully, but it doesn't show up in Windows Explorer. After investigating with Device Manager I find that it is read under successfully Disk Drives but it is not added to Storage Volumes, instead there is an Other Devices section with an unknown device in it. This is confirmed by diskpart which shows it when the disks are listed but not when the partitions are listed.

    When I go to disk management it does show the usb as Disk 1 but no letter is assigned to it. If it try to assign a letter to it (or do anything but eject it) then I get an error telling that the operation failed because the console view is not up to date.

    I've been working on this for the last day so any help or advice would be appreciated.

    Cheers,
    Murragh

    Few things you can check on. Download and install USBDVIEW run as the Admin. What your looking for is how many disconnections you have X. Those need to be removed. After doing so your reboot the laptop. If your issue is still present?

    You would go into System device manager and remove all USB controllers (don't delete) just remove so that Windows 7 can rebuild them when you reboot after you remove them.

    Hi,

    Thanks for the reply, unfortunately it still isn't working after both of the above solutions. I've taken a few screen shots that may be of use.

    USBDEVIEW after I had removed all the disconnections: http://sdrv.ms/ZfTN3I

    Device Manager : http://sdrv.ms/17RT6Rk

    Disk Management : http://sdrv.ms/1095WDe

    The strangest thing is that I have one usb stick that works, I've tried about 10 others and they don't work but it reads one usb stick correctly.

    Thanks
