    i'm having problem with my usb ports, They're properly installed so windows says,
    Its a DELL Inspiron 1150 notebook, The USB is Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD

    The others are

    Intel(R) 82801DB/DBM Universal Host Controller - 24C2
    Intel(R) 82801DB/DBM Universal Host Controller - 24C4
    Intel(R) 82801DB/DBM Universal Host Controller - 24C7

    I only have 2 USB ports but theres 4 installed o.o
    I have unistalled all of them, but they automaticly re-install
    I need help,
    I had them working before but i left it on all night before and they just stoped working

    When I plug in my mp3 it charges the battery but wont read it as any USB device and doesn't put it as a removiable disk,
    When i plug in my wireless mouse it has the lights go on but it doesn't read it or install as if you put any new USB device in, it gives power but wont pick up anything,
    I put in my wireless USB, and installed it using a disk doesn't pick it up or install the drive, basically my USB wont work and i have them installed Device manager says they're working properly, so if there is anything that can help or if somone has experianced this problem can help me.

    If you have XP, make sure you have Service Pack 1 or 2 installed. You can download them at http://windowsupdate.microsoft.com
    If you have Windows 2000, make sure you have Service Pack 4 installed.
    These service packs come with drivers for USB 2.0
    If you have the service pack(s) installed already, you may want to reinstall them, or repair Windows using your Windows CD (see sticky thread at top of these forums for help with that; it does not touch your personal files).

    First step, Start, Programs, Accessories, System Tools, System Restore. Create a restore point and name it something like "Before USB Fix". This is to bail you out if something goes wrong during the following process and makes things worse.

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG

    -------------------------- Use text after this line --------------------------------
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

    -------------------------- Use text before this line --------------------------------

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

    Reconnect the USB devices and see if they're recognized properly.

    NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

    Still nothing, I did the reg fix unistalled everything and rebotted twice nothing happen to the usb, I'm using Windows XP SP2.
    maybe fried? bad connectors?
    but i dont get why they give out power its just doesn't say when i plug in a new device "Found new hardware" "Logictech USB mouse"
    the lights will turn on but wont install the device, so the devices are render usless on this laptop.
    Also why does it have 4 USB installed but only 2 ports?
