Don't Comfort Curve 2000 (USB) some keys no longer recognized

Comfort Curve 2000 (USB) has recently ceased to recognize all keys when it is installed on my Toshiba Satellite laptop - Win 7 ~ 64-bit.  You wonder if it is related to a recent Windows Update.  (Only change I can think of) Usually, I prompt to install Win Update but a recent program by default to auto on the issue of the update. Something like 35 updates have been installed and the problem started.  Think that question is related to one, but cannot be isolated.  Similar problems exist with other USB keyboards, so it does not appear that the material. The problem looks like this: the prblem lks like that which presents a prblem 12467890... period and semi colon as it does not work.  No matter what usb that I use AND does not affect the frame to the keyboard on the laptop.

  • Combination of weird keys Comfort Curve 2000

    Hello

    I have a 2000 keyboard, comfort curve, which I like to use. He has a very odd behavior that I eventually tracked down.
    When you type, if I press "n" then "s" then "space", it acts as if I had just pressed the button back to iTunes.
    If someone else has reported this? How can I turn this off?

    Hi Ben,

    Thanks for a quick update.

    As the problem is specific to this keyboard, it could be because of problems with the driver for the keyboard.

    I suggest you to uninstall the current version and install the latest version of the driver for the keyboard. You can check the link to download the latest driver on Microsoft hardware Web site:

    http://www.Microsoft.com/hardware/en-in/d/comfort-curve-keyboard-2000

    Check out the link to open the Device Manager:

    http://Windows.Microsoft.com/en-in/Windows7/open-Device-Manager

    Follow these steps:

    (a) in the Device Manager window, locate the icon for the keyboard device and expand the driver icon.

    (b) make a right click on the driver icon and select uninstall.

    (c) follow the instructions on the screen to uninstall the driver.

    (d) find the folder that contains the configuration file for the most recent driver that you have downloaded.

    (e) double-click the installer and follow the on-screen instructions to install the driver.

    Check if you find always the same question. If so, it could be a hardware problem on the keyboard.

    I suggest you to contact the Microsoft Hardware support for further assistance. Check out the link to contact:

  • Some keys no longer work on Satellite A200-196 after Windows 7 update

    Hi all, I've just upgraded computer laptop of my partner (a Toshiba Satellite A200-196) to Windows 7 after you initially install Windows XP on it (it came with Vista).

    After the XP update, I noticed that some keys were not working. I don't remember the process that I used to solve the problem, but the difficulty that I did, and they were all soon works perfectly. So this is a software problem and not material. I think he might have something to do with the FN key - but I can't be sure.

    Now, I just upgraded the same machine and I have exactly the same problem. Keys that don't work are Backspace, O, P, F, H, K and L.

    Can anyone help please? I tried to reinstall Win7 and the problem is still there.

    Thank you very much

    Andy

    > The keys that don't work are Backspace, O, P, F, H, K and L.

    These keys have nothing to do with the missing software.
    Indeed, the function key (FN key) needs a Toshiba utility particular installation / software to make it work, but the keys Backspace, O, P, F, H, K and L are common keys on the keyboard that don t need no special software.

    That's why I think that the problem is hardware related: simple keyboard malfunction.
    I guess that all of these keys work correctly if you sign in and use the external USB keyboard.

  • Comfort Curve 3000 keyboard and Intellitype

    I just bought a Microsoft Comfort Keyboard 3000 and was assuming that it works with the Microsoft Intellitype software. However, Intellitype 8.2 does not have a Microsoft USB keyboard (the CC3000 is a Microsoft USB keyboard).

    The Comfort Curve 3000 displays as a Comfort Curve 3000 in devices and printers (my old keyboard doesn't have), however, in the Device Manager it is simply shown as a device HID keyboard (with a former driver of 2006). Make a driver search can't detect no other driver, any more than Windows Update.

    Interestingly, the Comfort Curve 3000 on Microsoft Hardware download page does not list Intellitype (made the comfort curve 2000). Can I get my Comfort Curve 3000 to work with Intellitype?

    I am slot as Windows 7 Professional 64 bit.

    Hello

    Since the Microsoft Comfort Curve 3000 keyboard requires no Intellitype software to make it work, the software does not recognize the keyboard.

  • 'Comfort Curve Keyboard 2000' cannot start (code 10)

    Hi, my laptop cannot detect my external keyboard. The keyboard is the 'Comfort Curve Keyboard 2000'. Laptop is an ACER ASPIRE 5738 G running Windows 7, 64-bit, the publishing house.

    When I plug in the keyboard, Windows says it can't find a driver for the device and if I manually select HID keyboard driver, Windows indicates that the device cannot start (code 10).

    I already tried to uninstall all USB devices and restart the system, but it did not work.

    Any suggestion?

    Hi Stefano,

    If the device has a FailReasonString value in its hardware key, that string is displayed in the error message. The driver or enumerator places this registry string value there. If there is no FailReasonString in the hardware key, you receive the following error message.

  • Some keys don't work no and Satellite M30 - 10 beeps

    Hello

    I have a weird problem on my Satellite M30-10seven.

    When I press some letter keys on the keyboard, that they do not work and the laptop will beep.

    It started with miuj updown seven point eight right has failed.
    But now I did and by commas and down and 8 make too as well as right.

    I also choose the Boot option to the power upward I never had before and sometimes internet explore trying to full screen.

    Probably not a key is pressed? Because as I said affect only some keys.

    Since writing this j stopped again.

    Any ideas?

    Try an external keyboard and see if that fixes the problem. If so, your keyboard needs to be replaced. If this is not the case, the keyboard on the motherboard controller has gone bad and you need a new motherboard. Also, try to download the update to the BIOS and see if that fixes the problem. Good luck.
