Laptop usb not working?

    I think there is something wrong with my laptop usb ports, but I am not 100% sure. I have tried to connect multiple mouses to my laptop but they are working like 50/50. Sometimes it works, and sometimes it doesn't. I tried to connect it to my computer and it just worked perfectly. When I use my laptop at work, my mouse never suddenly stops working. I really cant make a connection of what is going wrong. When it suddenly doesn't work I get a message with: USB device not recognized Now I have 3 usb ports.

    1: When I connect a mouse to it, it will light up and immediatly stop. Then it gives me the message: USB device not recognized

    2/3: When I connect a mouse to it, it will light up and quickly go on/off again and the mouse wont work. When I position the cable of the mouse differently, It will work(can be for hours) then all of the sudden it could just stop working again.

    What is going wrong?

    The above is with one mouse atm.

    I tried it with another mouse and the mouse light would just keep being on but it wont work. I took the mouse (which light just goes on an off again) to work and it worked perfectly for the whole day in all the usb ports.

    I'm guessing there's a bad connection that makes any usb device plugged in lose power when it's not in the right position. Have the ports been over-used? Is this an old laptop?
    If I'm right, a solution might be to buy an express-card (or pcmcia, depending on how old the laptop is) usb hub and use that.

    Found some on ebay:

    I've used the 54 mm one for a couple of years now, and it works perfectly. Hope I helped.

    windows - USB Microsoft Basic Optical Mice no longer working on laptops, but do work on desktops
  • Swanny

    We have a few HP laptops with Microsoft Basic Optical mice, the mice for some reason no longer work on the laptops but do work on desktops, this has only occurred this week. When I plug in the mice the optical light underneath do not light up and I receive the error:

    'USB Device Not Recognized: One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.'

    When I click on it the USB Root Hub lists Unknown Device, any ideas? I'm running Windows XP SP3 with latest updates applied.

    The fact that it happened to several laptops at once would seem to indicate that a software patch might have been installed across the group recently that is interfering with the driver for the mice. If there was a recent software or security patch, try rolling it back on one of the machines as a test. You might also try downloading and reinstalling the Microsoft Intellipoint mouse driver software

    I don't know if this is your problem, but I had a similar problem. I took my laptop to my specialist and was informed that, even though I had a powered hub, the fact that I had so many devices plugged in reduced the power available. I still get this message occasionally, but it does not disrupt my use. Good luck
