    Hi,
    I tried plugging in my usb mouse on my laptop yesterday and I could not get it to work. I'm not sure when it started since I don't use it often. I went on Device manager and found that 7 lines had an exclamation mark next to them:
    Standard Enchanced PCI to USB Host Controller
    Standard Enchanced PCI to USB Host Controller
    Standard Enchanced PCI to USB Host Controller
    Standard OpenHCD USB Host Controller
    Standard OpenHCD USB Host Controller
    Standard OpenHCD USB Host Controller
    Standard OpenHCD USB Host Controller

    When I double-click on each one of them, it says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

    I tried Update Drivers-> Search automatically for updated driver software, but they all say the best driver is already installed.
    I went on Windows Update, and installed each updated, but that didn't changed anything either.

    I tried to right-click and uninstall each one of them, and then reboot the laptop, hoping it would reinstall itself, but each time, there's a message that says it failed.

    I read somewhere that if I installed a driver for the PS3 controller it might have caused some problems, but I never plugged in anything else than my mouse and my ipod.

    What should I do? My laptop is a HP G62-224CA Notebook PC with Window 7 64-bit pre-installed

    Thanks

    The easiest way to resolve this is "Start,Programs, Accessories, System Tools, System Restore" and choose restore to a date prior to these issues starting and then do it. And whatever you do, in the future "pass" on Windows Driver Updates through Windows Updates as well.

    I tried "Microsoft Fix It" from the link but the problem is still here. Basically, it tries to reinstall those 7 lines but here's what it shows http://img208.imageshack.us/img208/9210/failpp.jpg

    As for the system restore, I updated my BIOS because it was a recommended update from HP Advisor(program that came with laptop), I was wondering if it is still okay? and by " "pass" on Windows Ddirver Updates through Windows Updates", do you mean to skip all the updates if there's any in the futur?

    Delete these devices in Device Manager and reboot to see if they install properly

    hm.. Not sure why, but the oldest one I found was from January 18 2011 and there's none other when I tick "show more restore points", so I took that one, the problem is still there, I think I should restore it to an earlier date, any other way to do it?

    Without more restore points, you are stuck with reformat and reinstall I'm afraid if you can't find any older restore points.

    A repair install might work, if you have a Win7 disk.

    Yeah it worked!! I did a System Recovery and now everything's back to normal :D
    I'm not sure what was the cause though, but isn't there a easier way to fix a corrupt registry?
    Either way, now should I install the updates from windows updates and HP Total Care Advisor?

    I don't trust either of those.
    Review their suggestions before installing.
