This chapter reports the use of speech as an input and output medium, in the General Intelligent Driver Support (GIDS) project of the DRIVE programme. One of the aims of GIDS is to identify techniques for supporting driver interaction with a range of in- car electronic devices. Then it allocates a new input device structure with inputallocatedevice and sets up input bitfields. This way the device driver tells the other parts of the input systems what it is - what events can be generated or accepted by this input device. Our example device can only generate EVKEY type events, and from those only BTN0 event code.

From the Device Manager on the copy of Windows which needs the driver, if you can navigate to the DriverStore folder of another Windows installation where the driver is located, then the Device.

Quite often Windows users facing a problem when the system can’t identify the connected device. In such cases, the Device Manager contents an Unknown device and the next information displayed in its Device Status box: The Drivers for This Device Are Not Installed. (code 28).

Such error is related to Device Manager and it’s important to mention that in most cases Code 28 means that you don’t have the latest device’s drivers installed on your machine and all you need to do is just install them.

How to Fix The Drivers for This Device Are Not Installed Code 28?

Solution 1. Update Drivers for the Device

This method will be useful in case you know which device causes the issue or you even have its manufacturer’s CD with appropriate drivers to install. All you need to do is to install drivers on your PC.

In case you don’t have such CD – you can download the latest drivers from the manufacturer’s official website.

Follow the instructions:

1. Download the latest drivers manually from the manufacturer’s official website. Run setup.exe or other executable files that you’ve downloaded;
2. In case there is no executable file in your downloads: run the Device Manager (run Command prompt, then type in and run command msc), find the needed device in the list. Right click on it and choose its Properties. Now switch to Driver tab and press Update Driver button.
   
3. After that – follow the installation wizard’s instructions and install the needed drivers.

Solution 2. Find and Install the Needed Drivers by Using Device’s ID

In case the device is not identified and you don’t know exactly what device causes issues, you might need its ID to try to find the needed drivers. To find out the ID of the device follow the instructions:

1. Go to Device Manager, find the Unknown device in the list, right click on it and choose its Properties;
2. In Properties switch to Details tab, now switch parameter in the field to Hardware IDs;
3. As a result, you will see a few IDs. Almost every ID has some deeper information about the device. Now we are going to search the drivers by using the ID – right click on it and press Copy;

We’ve found the ID of the device, now we need to find the needed drivers. The first thing – we will Google the ID to find the name of the device (or even a link to download the driver). When you got the name of the device – try to download the drivers from the manufacturer’s website or a third-party website (do it at your own risk!).

In case you can’t find them using the official website, try to use, as example, this website.

It has a great search option, you just need to paste the copied ID of the device into the search field and press Search. In case the drivers are in the website’s database—you can download the drivers directly from the website using the appropriate icon.

Solution 3. Try to Install the Needed Drivers in Compatibility Mode

Sometimes older drivers’ versions can be successfully installed by using the Windows compatibility mode. In case you have the drivers’ installation file (for example, on manufacturer’s CD) which causes errors – try to use the next method.

1. Open the folder where the drivers’ installation file is located, right click on it and then choose its Properties;
   
2. Now switch to Compatibility tab;
3. Check on Run this program in compatibility mode for: and try different OS versions (most often users are successful with Windows Vista).
   

Solution 4. Use Fix it (Automatic Tool)

This is an automatic tool to fix the Code 28 issue. All you have to do is to download the Fix it utility from the below link and install it in your computer.

• Download Fix it from here;
• Install it on your computer;
• Launch it and you will see the next options:
  • Hardware devices are not working or are not detected in Windows;
  • Diagnose and fix Windows USB problems automatically;
    
• Choose any of the options above;
• The rest of the work will be done automatically.

Additional Methods on How to Fix Code 28

In case the error Code 28 didn’t disappear after you tried all of the steps above, you can perform one of these additional methods:

Roll Back the Driver to the Version Prior to Your Update;

1. Run the Device Manager;
2. Right click on the device which you want to roll back the driver and open its Properties;
3. Switch to Drivers tab;
4. Click the button Roll Back Driver.

Using System Restore to Undo the Changes

In case you’ve created the Windows restore points earlier – it’s the best time to recover recent Device Manager changes by using it. Error code 28 should disappear after that.

Tip. It’s better to perform a backup of your drivers from time to time because it can help you to restore the correct functioning of the hardware and devices (USB devices, scans, printers etc.) quickly.

You can use Audio MIDI Setup to configure audio input and output devices that you use with your iMac, such as microphones and multichannel audio interfaces. Audio MIDI Setup works with many types of audio and MIDI interface devices, including your computer’s built-in audio and digital multichannel audio devices. It works with devices connected to your iMac using FireWire, USB, Bluetooth, PCMCIA, and PCI.

The settings you can change in Audio MIDI Setup depend on the audio device you’re using. For example, if the device supports volume control, you can adjust the volume for each channel your audio output device has available by following these steps:

1. Connect your audio devices to your iMac. If necessary, install any software included with the devices. See the documentation that came with your audio devices.
2. Open Audio MIDI Setup (you can find it in Utilities, inside your computer's Applications folder).
3. Choose an audio device from the list on the left side of the Audio Devices window.
   • To use the device for sound input, choose 'Use this device for sound input' from the Action pop-up menu.
   • To use the device for sound output, choose 'Use this device for sound output' from the Action pop-up menu. If you also want to use the device to play system sounds, choose 'Play alerts and sound effects through this device' from the Action pop-up menu.
4. On the right side of the Audio Devices window, choose the options available for the device you're setting up:
   • In most cases, leave the 'Clock source' pop-up menu on the default setting.
   • To set up surround (multichannel) speaker configurations, click Configure Speakers. Then, choose the type of configuration you want to use. See Set up external speakers for stereo or surround sound for more information.
   • You can set the sample rate and bit depth in the Format pop-up menus. Make sure they match the appropriate settings for your audio device and that the input and output sample rates are set to the same value. For example, the built-in speakers of an iMac computer may appear like this:

• If your iMac supports the hardware sample rate converter, the Hardware Rate Converter pop-up menu is available in the Input menu. When you choose Automatic from the pop-up menu, the hardware sample rate converter is turned on if the audio samples coming in are PCM and formatted according to the international standard IEC 60958-3. The hardware sample rate converter is turned off if the input stream is encoded. You can also choose Enable or Disable from the menu to keep the hardware sample rate converter turned on or off.
  If you choose Enable from the menu, you may not be able to stream non-LPCM or encoded audio because the audio may not be recognized.
• If software volume control is available for your device, the Volume sliders are blue to indicate they are active. Drag the sliders to set the volume for each channel.
