Registering a WDM Smart Card Reader Driver
To make a smart card reader driver visible to 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, use a Start value of 3 to make 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 SmartCardReader setup class, because the smart card resource manager waits for this class to start. |
ErrorControl |
DWORD:0x0000001 |
A value of 1 shows an error message if the driver fails to load, but lets the system continue to start up. |
