On a computer that is running Windows Vista or Windows Server 2008, you open Device Manager to review the properties of a driver. However, the Digital Signer field on the Driver tab displays the following status message:

Consider the following scenario. On a computer that is running Windows Vista or Windows Server 2008, you successfully install an earlier (legacy) version of a particular wave driver. In Device Manager, this driver is shown as being installed correctly. However, under certain conditions, an application that has to load this wave driver cannot find it.

If you use a debug tool, such as WinDBG, to troubleshoot the issue, you will notice that the user-mode wave driver does not load as expected.

Consider the following scenario:

• On a Windows Vista-based computer, you install a signed driver.
• You open Device Manager, and then you click the Driver Details button on the Driver tab.

In this scenario, the Digital Signer field for the device displays the following status message:

Not digitally signed

However, when you right-click the properties of the device on the main Device Manager tab, a message is displayed that states that the driver is signed.

The Microsoft Storport driver (Storport.sys) is installed on a computer that is running Windows Server 2008 or Windows Vista. Then, you notice that the value of the DeviceType registry entry for storage devices is truncated to half of its length.

Note The DeviceType registry entry is located under the following registry subkey:

HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port [x]\Scsi Bus [x]\Target Id [x]\Logical Unit Id [x]

In this subkey, [x] is a placeholder for a one-digit number.

For example, the value of the DeviceType registry entry may be truncated to “MediumChang” when the registry entry that is expected is “MediumChangerPeripheral.”

Therefore, applications may function incorrectly when they retrieve the device type information from the DeviceType registry entry.
