To make a smart card reader driver visible to the device manager, you must put the indicated registry values under the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SmartCardDriver
The required values are listed in the following table.
| Registry Value Name | Contents of the Registry Value | Meaning |
|---|---|---|
| Start | DWORD:0x0000002 | A value of 2 makes the driver start automatically. During development, you should use a Start value of 3, which makes the driver start manually. |
| Type | DWORD:0x0000001 | A value of 1 identifies the driver as a kernel-mode driver. |
| Group | SmartCardReader | Every driver has to be a member of the setup class SmartCardReader, since the smart card resource manager waits for this class to start. |
| ErrorControl | DWORD:0x0000001 | A value of 1 lets the system continue to boot even if the driver fails, but it shows an error message if the driver fails to load. |
