Add New Hardware Error Message

"Found New Hardware Wizard" advises, "Cannot install this Hardware. There was a problem installing this hardware: PCI Simple Communications Controller. The data is Invalid.
This is caused in XP by the new PCI Registry entry defaulting to "Read" under Permissions. Also, the Device Manager shows the typical yellow query against other Devices/PCI Simple Communications Controller.
Suggested Solution/Fix:Go to Start/Run/Regedit and navigate to this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI
Open each sub-key: Ven_XXXX... In the right pane read the Value Data for each DEVICEDESC, until you find your modem. Once found, right click the 3&71aaa sub-key and select Permissions and under the word "Allow", select "Full Control", click OK then go to File/Exit.
Then go to the Device Manager, right click on the device name that matches the "DEVICEDESC" value you changed in the registry. Select Properties/Driver/Update Driver. Windows will now ask you for the disk or CD-ROM that contains the driver for the failing device.
This error can also occur when configuring drivers for a such as SCSI cards, Network cards, Sound Cards, or other peripherals. This symptom appears to occur when there has been a recent hardware configuration change within Windows XP. This error is believed to be due to an issue occurring when hardware enumeration takes place by the operating system.
