    USB ports not working - Standard Enhanced PCI to USB Host Controller issue

    USB.JPG
    Hello!
    Attached is a picture of how my Device Manager currently looks.. Both of my USB ports do not work. (Upon restart or USB re-entry, a pop-up comes up with "USB Device Not Recognized"). Under the host controller's properties: "This device cannot start (code 10)".

    About a few months ago, my laptop (Toshiba, Satellite L505) was struck with the knot of a rope on the upper left corner of the base (to the right of the speaker, right above the button F4), and it made a buzzing noise for a couple minutes, then stopped. Ever since then, I've had my sound and USB ports messing up - my sound has had a red X through the icon on the bottom right, and in the Device Manager the 3-4 Standard OpenHCD USB Host Controller usually appear like the above, but to fix that I've just uninstalled them, rebooted, and let the computer reinstall them and it's fine. The sound problem goes away somehow too but has also reappeared. This time it's a tad different, and I don't want to mess anything else up :]

    I'm probably missing information here - please ask for anything I left out! I deeply appreciate the help!! :]

    Software cannot fix broken hardware.

    Yes, I was afraid it was a hardware damage; probably just need to take it to an expert and have them disect it and take a look at everything. Thanks for your reply!

    Have you tried to remove the inoperable devices through device manager, then reboot to see if new devices are seen and the drivers loaded? Might be worth trying to save a few bucks that a tech would charge.

    You might also want to try updated chipset drivers for your PC. Check the support page for your PC vendor or motherboard.

    What is commonly not understood is that USB ports fail. I have had a number of USB cards installed and when one of the circuits failed, it gave me problems booting my rig. If you have one of those seven port USB devices or even a two port USB device, sometimes the devices simply go poof and simply stop working. If you have a built in USB device such as built into your computer case, you may be able to get replacement parts and sometimes you can't.

    The other thing to remember is that when you have a USB device which is plugged and unplugged a lot, sometimes those little square risers come loose. You'll also find that the electrical connection in the device sometimes gets very raggedy and simply stops working.

    The other issue is that sometimes the USB port "tries hard" but you may not have enough power going through the circuit and eventually the device fails. When you buy an external USB device, if at all possible make sure that you have a power adapter to go with it. A USB card on your motherboard will be charged by the motherboard and sometimes there are power problems there as well because nothing in computers "does everything".

    It is "just one of those things" that happens to machines; parts wear out.

    Ethan,

    Hello... If it were my PC i would do the following.....

    1. Open-er-up and have a "look see" check for anything cable related.... loose, disconnected , etc.

    2. Try to re-seat them , or anything else that can be.

    3. Could be that something was jarred loose from the impact ...not likely that all USB ports would be damaged ... Regards Fred

    Tried that a few days ago - uninstalled the inoperable devices, reboot, but the devices couldn't reinstall themselves.

    Ethan,
    Hello.. I know this is a "Long Shot" ..but i would try it ...

    1. Right click on the devices with the "Exclamation Mark" and click to either disable or uninstall each..

    2. From an "Elevated Command Prompt" ( right click run as administrator) input "sfc /scannow" No quotes and space after sfc..

    3. Reboot and post back with results Regards Fred

    [SIZE=4]If your device is an external hub, you may have to replace the hub. If your device is a USB port installed inside the case, you may have to open the case and see if the headers (cables attached to the motherboard) are loose. Cables DO work themselves loose over time or are just loose. If the USB device is a USB card in a PCI slot, it may have to be replaced. Also you may have a driver problem. Drivers do get funny with Windows updates. I have a scanner that worked just fine and then after an update windows would not recognize it and I have to get a newer model scanner.

    You may also want to check USB cables as IO have had to replace them here and there. They do go poof from time to time; it will surprise you.

    Make sure the device is turned on ... not just that the power light is on but that it "does something" to check that power is coming to it.

    Failing all this, I agree that you need to uninstall the drivers, disconnect everything and start as if it were day one.

    You may want to get driver fetching software. I use Avanquest as my source of 2nd tier stuff.

    Ethan,

    Fred,
    Haha that's alright! I will probably take it to a tech near my location soon, as I would like to make sure no damage has been done to anything beneath the surface.. Thanks so much for your help! Let me know if you think of anything else :]
