Hello

1. what operating system is installed on your new computer"? XP, Vista or Windows 7?
2 do you see anything unusual (yellow bang) in Device Manager?

Assuming you are using XP (because the thread is in the XP category), I suggest you follow the steps below.

Step 1: Use Device Manager to find the hardware changes
Use Device Manager to find the hardware changes. After your computer search the hardware changes, it can recognize the USB device connected to the USB port so that you can use the device.

To check the hardware changes, follow these steps:

a. Click Start and then click Run.
Note If you are running Windows Vista, click Start and then use the search box.
b. type devmgmt.msc, and then click OK. Device Manager opens.
(c) in Device Manager, click on your computer so that it appears highlighted.
d. click Action and then click Scan for hardware changes.
e. check the USB device to see if it works.

Step 2: Remove and reinstall all USB controllers

To remove and reinstall all USB controllers, follow these steps:

a. Click Start, click Run, type sysdm.cpl in the Open box and then click OK.
b. click on the Hardware tab.
c. click the Device Manager button.
d. expand Bus USB controllers.
e. right click on each device under the Bus USB controllers node and then click on uninstall to remove them one at a time.
f. restart the computer and reinstall the USB controllers.
g. plug in the removable USB storage device and perform a test to ensure that the problem is solved.

    The only way to install an ipad app is through the app store.  PC or Mac software does not run on the ipad.  Search in the contacts link at the bottom right of this page.  Give apple a call.

    I guess is the icon for pages in icloud for storing documents pages.  At the same time, apple had a cloud based pages.  Not sure what happened to her.

  • USB devices that are always hidden/not recognized on Satellite C50-A-1Jn

    Hi, hope someone can help!

    I have scoured the internet for a resolution of this problem but found nothing so far.

    Basically, I had used a hard drive on this laptop a few weeks before all of a sudden, it stopped being recognized. The hard drive light blinking always however. The hard drive has since the same thing on every PC. I thought that it was a broken hard drive BUT I tried since two of the iPhone, both of which are also unknown, BUT they will be responsible.

    I tried on other computers of the iPhone and both are very good.

    The furthest I got is to know that the hard drive is listed in Device Manager when I show "hidden devices", but I can't use it or hide from the United Nations.

    Does anyone know how to fix this? If you need more info please let me know.

    Thank you.

    If I understand you just your laptop does not recognize the external devices connected to the USB port.
    Is the same problem with all the USB ports?

    Do you use the preinstalled original Win8.1 64-bit, that you got with your machine?

    The program is FREE.

    Here is the link to download MSE, Microsoft Security Essentials:

    UNINSTALL any "windows key vista (version)" you have, if you don't find in your application programs and features.

  • PS CC 2015 stops working with the message after a minute or so below.

    Adobe Photoshop CC 2015 has stopped working.

    Looks like that it crashes when closing the files.

    It must still go to the Appdata folder, then go into the path: Roaming\Adobe\Adobe Photoshop CC2015\Auto recover

    Move all the files under auto recover on the desktop

    Then, launch Photoshop and go in Edition > Preferences > Performance > uncheck the option to use the graphics card processor

    Click OK and restart the application Photoshop

    Try to work in and it should work fine now.

    This means that the problem is related to the graphics card so, you will need to update the graphics card drivers.

    Also, if you want to go back to version CC2014, you can follow the steps to install the previous version app in this artcile:

    I have Acrobat 9.5 and when I try to create > pdf from a scanner, it shows an error "Adobe acrobat has stopped working". Is it possible that I can use this feature?

    Providing you have Acrobat 9 installed in an operating system for which Acrobat 9 is compatible then you can use the feature.

    So, you need a scanner connected, turned on, and the software installed. Acrobat 9 "prefer" TWAIN drivers.

    Always visit the site of the provider of the Analyzer and download - install the latest version of the greatest software.

    n.b., The Acrobat 9.x product family moved in the middle of the "End of Support" year 2013.

    Thus, the family of products Acrobat 9.x is not compatible with contemporary operating systems.
