Enabling Smart Card Event Logging in the Registry

  • Artikel

Smart card reader drivers should log errors in the system event log so that the system administrators can use the log to help diagnose why a driver fails.

To enable event logging, you must add several values to the registry under the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\EventLog\System\ SmartCardDriver

The registry values that enable event logging are listed in the following table.

Registry value name Contents of the registry value

EventMessageFile

%SystemRoot%\System32\Drivers\SmartCardDriver.sys

Important   The file name extension must be included in the EventMessageFile value name, but it must never appear in any other part of the registry path.

TypesSupported

DWORD:0x00000007

For more information about specifying these registry entries, see INF AddService Directive.
