Logitech iTouch Driver Update

October 15th, 2009 No comments

Logitech International is a well-known provider of computer peripherals as well as other digital devices based in Romanel-sur-Morges, Switzerland. The company creates and markets products like keyboards, mice, game controllers, microphones and webcams for computers. Logitech also develops home and computer speakers, headphones, wireless audio devices as well as audio devices for mobile phones and media players.

Aside from its headquarters in Switzerland, the company also has offices throughout Europe, as well as in Asia, Fremont,California and in other parts of America. Logitech’s marketing activities and sales are classified into four geographic regions: EMEA, Americas, China and Asia Pacific.

Among the popular products from Logitech are the iTouch keyboards. This keyboard series is brilliantly designed to enable the users to access the Internet, search, open e-mail and open applications with a single key press. The iTouch keyboards also feature one-touch multimedia control and a comfortable key design for an excellent typing touch. Some iTouch keyboard models come with built-in USB ports that let you connect additional devices to the keyboard as well as a unique cable management system keeps your workplace free of messy cables.

In order to enhance the performance of any Logitech iTouch keyboard, you can download its driver from this link. It is highly recommended you install the driver version 2.2.289 (October 15, 2009). This software is compatible with Windows 95, Windows 98, Windows 2000, Windows NT as well as Windows XP.

To protect your computer from incorrect installation, try to set a system restore point whenever you install a new driver update. This will prevent your computer from malfunctioning in case the wrong driver is installed. Problems usually occur when the hardware is too old or no longer supported.

Aside from updating your Logitech iTouch keyboard, remember to keep the other hardware on your computer working with the latest drivers.

Problems with a specific USB device in Windows XP

October 12th, 2009 No comments

USB problems are usually an easy problem to solve. First, isolate the problem. Unplug all USB devices from the system, including USB hubs. Next, take a known good USB device and attach it to the system. If the known good device works, then you can be sure that there is nothing wrong with the port itself.

Now take the device that was malfunctioning and plug it directly into one of the computer’s USB ports while no other USB devices are connected to the system. If the device starts working, the problem most likely was that device was conflicting with another USB device. One way that USB devices can conflict with each other is if they share a common serial number. Each USB device in a system must have a unique serial number. Having two devices with a common serial number is very rare, but there are documented cases of it happening.

If the device now works and it isn’t sharing a serial number with another device, it was probably malfunctioning because of an overloaded USB hub or a conflicting device driver (Click here to run a scan for updated drivers). The only real way to sort out the problem is to use trial-and-error by plugging in various combinations of USB devices until you find the device or devices that the malfunctioning device is conflicting with. Once you track this down, you can usually solve the problem by moving the devices to different physical USB ports or by updating the drivers for both devices.

What if plugging in the malfunctioning device without any other USB devices being plugged in doesn’t cure the problem?

Try checking the computer’s Event Logs for clues to the malfunction. If the event log doesn’t give any clues, try plugging the malfunctioning device into another computer. If the device works on the other computer, then you can be sure that the device is good.

If the alternate computer is using an operating system other than Windows XP, the problem could be that the device or its driver isn’t Windows XP-compatible. Check to see if there are updates for your device for XP, if not, contact the device’s manufacturer to see if there are any known issues with using the device with Windows XP.

If the alternate computer is running Windows XP and the device is working, then I recommend checking out what version of the device driver is being used on each machine and using the one that works, even if it isn’t the most recent.

Code 31 Error in Device Manager

October 12th, 2009 No comments

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

A Code 31 error can be related to any hardware device, but most Code 31 errors appear on optical drives like CD and DVD drives. A Code 31 error is caused by a number of reasons that stops Windows from loading the driver for a specific hardware device. (The exception is if you see the Code 31 error on the Microsoft ISATAP adapter in Windows Vista. Microsoft claims that there is not an issue here. Just ignore the error.)

Try these solutions to fix a Code 31 error:

  • Restart your computer (Sometimes this will solve the problem and you’re done.)
  • If you just installed a device or updated drivers, they might be the cause of the problem. Undo the change, or roll back the drivers. (You can also try to use the System Restore to undo Device Manager changes)
  • Try to update the device drivers, either automatically or by downloading them from the manufacturer’s website.
  • Make sure that your device is compatible with whatever version of Windows you are running. Any of Microsoft’s operating systems can experience a Code 31 Device Manager error.

Device Manager Error Codes

October 9th, 2009 No comments

Device Manager error codes are codes, followed by error messages, that are reported in the Device Manager

Error codes in Device Manager are created when your PC is experiencing device driver issues, system resource conflicts, or other hardware problems.

Note: Device Manager error codes are completely different than system error codes even though some of the code numbers may be the same. If you see an error code outside of Device Manager, it’s not a Device Manager error code.

Error Code 3

October 9th, 2009 No comments

The Code 3 error is one of several Device Manager error codes. The Code 3 error will usually appear like:

The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3)

Important: Device Manager error codes are only seen in the Device Manager. If you see the Code 3 error somewhere else in Windows, it is most likely a system error.

What Causes the Code 3 Error?

A Code 3 error is generated when the Device Manager can’t start the device due to  outdated or corrupted drivers or poor system resources.

Resolution

  1. Restart your computer. There is always the chance that the error Code 3 you’re seeing on a device was caused by some temporary memory problem or an issue in the Device Manager or with the hardware. Sometimes rebooting your machine might fix the Code 3 error.
  2. Undo Recent Changes. If you recently installed a device or made a change in the Device Manager just before the Code 3 error appeared, then undo whatever change you made to see if the error is still there. Depending on the changes you made, you might try to:
    • Remove or reconfigure the newly installed device.
    • Roll back the driver to a previous version.
    • Use System Restore to go back to a date prior to your Code 3 error.
  3. Reinstall the drivers for the device. Uninstalling and then reinstalling the drivers for the device is a likely solution to a Code 3 error. (If a USB device is generating the Code 3 error, uninstall every device under the Universal Serial Bus controllers hardware category in the Device Manager as part of the driver reinstall.) It is important to note that a full driver reinstall involves completely removing the currently installed driver and then letting Windows install it over again from scratch.
  4. Update the drivers for the device. It’s also very possible that installing the latest drivers for the device could correct the Code 3 error. If it does, it means that the stored Windows drivers you reinstalled in Step 3 were were probably damaged.
  5. Install the latest Windows service pack Microsoft often releases service packs and other patches for Windows, one of which might contain a fix for the Code 3 error.
  6. Replace the hardware. A problem with the hardware device might be causing the Code 3 error, in which case replacing the hardware is your next logical step. Another possibility, is that the device is not compatible with your version of Windows. You can check the Windows HCL to be sure. If you’re positive that a hardware problem isn’t causing the Code 3 error, you could try to repair your Windows instillation. If that doesn’t work, as a last resort, you may need to contact a local repair shop or try a clean install of Windows.

Device Class GUIDs for Popular Types of Hardware

October 1st, 2009 No comments

Other than programming for a device driver, the Globally Unique Identifier (GUID) for a device class is useful when tracking down driver information in the Windows Registry.

For example, the solution to several Device Manager errors include removing specific registry entries after a device’s GUID.

Note: This is not a complete list of device class GUIDs. Devices can generate unique classes based on various variables making it virtually impossible to list them all.
