    PC not recognizing the USB device of mobile.

    I have an LG Viewty Smile mobile which came with an USB cable for connecting it to PC which has Windows 7, but I am not able to do that because whenever I insert this cable, the computer first of all shows "USB Device not recognized". I have tried it with all of port present in my computer but i always see the same message. Is there any way to solve this issue?

    Re: PC not recognizing the USB device of mobile.

    Are you getting a “USB device not recognized” error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!
    However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!
    So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn’t work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn’t work!
    I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!
    You may also see in Device Manager that the device shows up as an “Unknown Device”.
    So how did I finally fix the problem? Well, apparently it’s a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.
    Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that’s it! Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.
    First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!
    So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.

    Hi,
    As all the ports in your computer is issueing the same message and failing to recognize the mobile fone, be sure the problem is not in the PC.
    The problem should be in the cable that attach mobile with the PC change it to see the performance.
    You may also check after uninstalling and reinstalling the USB drivers. Disconnect all USB devices and then perform the following steps:

    Click Start, and then Control Panel.

    Click System and Maintenance, click System, then Device Manager.

    If Control Panel is in Classic View, double-click System, then Device Manager.

    If prompted for "administrator password" or "confirmation", type the password, or click Allow.

    In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the "Host Controller", click "Uninstall" then "OK".

    Check if there is an "exclamation mark along the driver", it suggests problem with the driver installed.

    Uninstall all items under "Universal Serial Bus controllers".

    Restart your computer and Windows 7 will reinstall all USB controllers automatically.

    If you still face the same issue then you must download the updated USB device drivers using windows update and install them.

    Thank you.

    Hi,
    Firstly, you need to install a PC Suite for your mobile.
    The PC Suite software might have come with your mobile phone.
    Then connect the phone and on the phone, select the option as PCSUITE.
    Your problem will be solved.
    Thank You.

    One way i can suggest is that you format your OS and again insert your usb cable and select mass storage and let your system recognize the usb when you will insert your usb cable your computer will say new device found don't close it until it says device installed and ready for use. I hope this will you

    Hello friend,



    I have the solution for your problem just do as i say........

    1.Firstly check that the USB cable is fine.

    2.Also check the USB port of your computer.

    If there is no problem in then do as i say below.

    For connecting a mobile to a PC you should need to install a software
    related to your mobile. You will get that software CD along with that
    mobile or if you do not have it you can download it from internet by
    going to 'www.filehippo.com'.

    Even if there is a problem then.

    1.Firstly make a right click on 'My computer'.

    2.there you click on 'manage'.

    3.Then you go to the 'Device manager'.

    4.There you make a click on '+' near the 'Universal Serial Bus Controller'.

    5.There you make a double click on any one of the 'USB Root Hub'.

    6.There you select 'Use this device (Enable).

    7.At last click 'Apply' and then 'OK'.

    I hope it will help you.

    Have a nice day...........
