Windows Server 2008 Inside Out- P6 Installing Devices 217One of the more common warnings you’ll see is related to you connecting Hi-SpeedUSB devices to non-Hi-Speed USB ports, as shown in the following screen. This isimportant because if you are connecting an external hard disk drive or other Hi-SpeedUSB device, the device won’t operate at the rated speed. It will in fact operate at a muchslower speed. Chapter 8USB 1.0 is the original USB specification. USB 2.0 is the newer USB specification,and it is referred to as Hi-Speed USB. Although you can connect USB 2.0 devices toUSB 1.0 ports, the devices operate at the USB 1.0 speed (which is many times slowerthan USB 2.0). If you want to achieve high-speed USB transfers, you must connect to aUSB 2.0 port, if available. You might also want to consider adding a PCI expansion cardwith USB 2.0 ports.Because of Plug and Play, you should be able to install new devices easily by using oneof the following techniques: For a non-USB or non-FireWire device, simply shut down the computer, insert the card into the appropriate slot or connect the device to the computer, restart the computer, and then let Windows Server 2008 automatically detect the new device. For a USB or FireWire device, simply insert the device into the appropriate slot or connect it to the computer, restart the computer, and then let Windows Server 2008 automatically detect the new device.Depending on the device, Windows Server 2008 should automatically detect the newdevice and install a built-in driver to support it as discussed previously. The deviceshould then function immediately without any problems. Well, that’s the idea, but itdoesn’t always work out that way. The success of an automatic detection and installa-tion depends on the device being plug and play compatible and a device driver beingavailable.Windows Server 2008 includes many device drivers in a standard installation, andin this case, it should install the device automatically. If driver updating is allowedthrough Windows Update, Windows Server 2008 checks for drivers automaticallyusing Windows Update either when you connect a new device or when it first detectsthe device. Because Windows Update does not automatically install device drivers,you’ll need to check for available updates to install the driver. 218 Chapter 8 Managing and Troubleshooting Hardware SIDE OUT Installing new drivers All device drivers provided through Windows Update have been thoroughly tested in the Windows Hardware Quality Labs (WHQL), and you should be able to count on them not to cause your system to crash or become unstable. However, just because driver updates are available doesn’t mean you should install them. In a production environment, you’ll rarely want to download and install new device drivers without thoroughly testing them yourself first. Better safe than sorry—always. Typically, you install new device drivers because you are experiencing problems with the old drivers or looking for new function- ality. If you aren’t experiencing problems or don’t require the additional functionality,Chapter 8 you might not want to update the drivers. If Windows Server 2008 detects a Plug and Play device after you’ve connected it but cannot locate a suitable driver, it displays a warning that a problem occurred during installation, as shown in the following screen: Sometimes when this happens, you must install the hardware device manually as you do with non–Plug and Play devices. See “Adding Non–Plug and Play Hardware” on page 235 for details. More typically, Windows Server 2008 starts the Driver Software Installation compo- nent, which in turn starts the Found New Hardware Wizard. In this case, you can com- plete the installation by following these steps: 1. In the Found New Hardware Wizard, click Locate And Install Driver Software (Recommended) to continue with the installation. 2. The Driver Software Installation component will then search for preconfigured drivers. If it doesn’t find a preconfigured driver, you are prompted to insert the disc that came with the hardware device. 3. Use one of the following techniques to continue: If you have an installation disc for the device, insert it and then follow the prompts. The device should then be installed properly. Skip the remaining steps. If you don’t have an installation disc, click I Don’t Have The Disk. Show Me Other Options and then follow the remaining steps in this procedure. 4. On the next wizard page, click Browse My Computer For Driver Software. 5. Click Browse to select a search location. ...
