Note You can also install Windows XP SP2, and then disconnect and reconnect the USB devices that are connected to your computer. By doing this, you start the Plug and Play utility. The Plug and Play utility updates the version numbers for the drivers.
The main reason for Unknown Device to display in your Device Manager is because you have a device that is not working correctly. To fix this issue, obtain an updated driver for the device.Use the following methods to enable Windows to recognize your device.

The device does not have a device driver: When a device driver for a device is not available, Device Manager displays the device as Unknown Device and puts it in the Other devices branch. This is very common with universal serial bus (USB) and Institute of Electrical and Electronics Engineering (IEEE) 1394 composite devices. Also, a status of Error Code 1 or Error Code 10 may be displayed when you view the properties of the device in Device Manager.Note Most USB and IEEE 1394 devices function correctly without additional device drivers because they are configured by the drivers that are included with Windows for these bus types. However, an additional device driver is needed if the device does not fit the defined and supplied Windows class drivers. If the bus cannot identify the device, it interprets the device as a composite device and then reports it as such in Device Manager.
You are using a Microsoft Windows 98 or Microsoft Windows 95 Device Driver: You cannot use virtual device driver (.vxd) files that are common to Windows 98 or to Windows 95 drivers in Windows XP. If you try to install them on your Windows XP-based computer, the device may be listed as unknown in Device Manager. This typically occurs when the device driver manufacturer does not correctly differentiate between the two drivers or assumes that Windows XP can use Windows 98 or Windows 95 .vxd files.
Unrecognized Device ID: Every hardware device has a special identifier that is used by Plug and Play. This identifier can include several different types, such as vendor ID, device ID, subsystem ID, subsystem vendor ID, or revision ID. If a device ID is not present, or your Windows XP-based computer does not recognize the device ID, Device Manager may list the device as unknown.Note Software programs that require virtual hooks into hardware may create these devices. Additionally, devices that bridge between bus types, such as a device driver that enables a parallel port device to emulate a SCSI or an AT Attachment Packet Interface (ATAPI) bus, are also known to generate an unknown-device response in Device Manager.
Faulty Hardware or Firmware: Faulty hardware or firmware may cause a device to be displayed as Unknown Device in Device Manager. Software-only device drivers do not expose a device ID, and there is no standard method for installing these devices. Some manufacturers install the device by using the InstallShield installation program or a similar method. Be aware that software installed by other methods may not be completely removed when the device is removed in Device Manager. Therefore, you may have to check the registry to verify that all entries are removed.
The Error Code column lists the error code associated with this specific problem. Frequently, the Device Manager error code helps determine what created the unknown device. For example, if your computer generates a "Bad or missing device driver" error message, three types of entries may be listed under Problem Devices, depending on the device type:
Determine whether the device driver is digitally signedWhen you install a device driver, and Windows detects that it is not digitally signed, you may receive a warning message and the option to cancel or continue the installation This message is displayed only if your computer is configured to display a warning message whenever an installation program tries to install a device driver without a digital signature.Note A device driver that is digitally signed can still be listed as an unknown device in Device Manager. For more information about driver signing for Windows, visit the following Microsoft Web site:
You can block the installation of device drivers that do not contain a digital signature. Use this approach when you want to prevent any deliberate attempts to destabilize the computer. To do this, follow these steps:
Installing section epatapi_inst from C:\documents and settings\user name\my documents\parallel port test drivers\epatapnt.infAn unsigned or incorrectly signed driver (C:\documents and settings\user name\my documents\parallel port test drivers\epatapnt.inf) was installed for Parallel ATAPI Adapter.. Error 0xe000022f: The third-party INF does not contain digital signature information.Copying file C:\documents and settings\user name\my documents\parallel port test drivers\epatapnt.mpd to C:\Windows\System32\DRIVERS\epatapnt.mpd.An unsigned or incorrectly signed driver (C:\documents and settings\user name\my documents\parallel port test drivers\epatapnt.mpd) was installed for Parallel ATAPI Adapter.. Error 0xe000022f: The third-party INF does not contain digital signature information.
Use the File Signature Verification toolThe File Signature Verification tool lists all the unsigned drivers that are installed on your computer. It creates a Sigverif.txt log that is located in the %SystemRoot% folder. Use any text editor (for example, Notepad) to view the file. To use the File Signature Verification tool to display a list of drivers that are not digitally signed, follow these steps:
USB devices that are based on earlier versions of the USB specification may create ghost devices that appear when the device is connected, and then disappear when the device is disconnected. Also, the device may work fine, but may create a disassociated unknown device. This is typically caused by firmware that is either outdated or configured incorrectly. In this case, contact the device manufacturer for updated firmware.A ghosted device can appear if you manually install a driver for a Plug and Play device that the computer has already detected and installed. You can resolve this issue by deleting the ghosted device.
We were unable to find drivers for your product. Try manually selecting your operating system. If your operating system is not listed then HP may not provide driver support for your product with that operating system.
If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter Sony PSP into the search box above and then submit. In the results, choose the best match for your PC and operating system.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.
If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter Datel WiFi MAX - PSP/DS into the search box above and then submit. In the results, choose the best match for your PC and operating system.
