當您將智慧卡插入 Windows 7 或 Windows Server 2008 R2 電腦上的讀取裝置時,出現錯誤訊息:「裝置驅動程式軟體未安裝成功」

徵狀
當您將智慧卡插入智慧卡讀取裝置時,Windows 會透過隨插即用服務,嘗試下載和安裝卡片的智慧卡微驅動程式。如果任何預先已設定的位置 (例如 Windows Update、WSUS、內部網路路徑) 都沒有智慧卡的驅動程式,而且系統沒有安裝自訂式密碼編譯服務提供者,則您會在通知區域收到下列錯誤訊息:
裝置驅動程式軟體未成功安裝
請按一下此處取得詳細資訊。
這個錯誤訊息會在數秒後消失。

此外,在「裝置管理員」的 [其他裝置] 下方,智慧卡裝置會有 DNF (找不到驅動程式) 的狀態。

這通常需要使用者向智慧卡發行者取得下列其中一個項目,才能解決錯誤:
  1. 有 Windows 標誌的智慧卡微驅動程式
  2. 智慧卡的自訂式密碼編譯服務提供者 (CSP)。
  3. 沒有 Windows 標誌的智慧卡微驅動程式
  4. 其他中介軟體,例如 ActiveX 控制項、PKCS#11 軟體或其他自訂式軟體。
但是如果只提供此清單中的項目 3 或 4 給使用者,則智慧卡仍會在系統上運作。使用者在每次插入智慧卡時,還是會收到本節提及的錯誤訊息。

這個問題會影響 Windows 7 的所有發行版本、Windows Server 2008 R2 和這兩個作業系統的更新版本。
發生的原因
所有的智慧卡都需要額外的軟體才能在 Windows 中運作,除非有內建驅動程式,讓使用者不必安裝額外的軟體就能使用卡片。Windows Smart Card Framework 在 Windows 7 中已大幅改善,當智慧卡插入讀取裝置時,會自動從 Windows Update 或其他類似位置,例如 WSUS 伺服器,下載智慧卡微驅動程式。所有成功通過標誌 (由 Windows Logo Program 核可) 要求的智慧卡都能從此功能獲益。

但是,如果要在 Windows 中使用之智慧卡的軟體沒有通過標誌、或是屬於與微驅動程式不同的類型,例如 PKCS#11 驅動程式、自訂式 CSP、中介軟體或 ActiveX 控制項,則自動下載選項會失敗,因為 Microsoft 只認證智慧卡微驅動程式。因此,如果使用者插入卡片、而卡片的自訂式 CSP 沒有登錄,即便使用者已透過自訂式安裝將額外的軟體安裝在電腦上,讓使用者透過該軟體使用智慧卡,使用者仍會收到錯誤訊息,說明智慧卡裝置的驅動程式軟體遺失。
解決方案
雖然使用者會看到錯誤訊息,但智慧卡仍可繼續運作,智慧卡發行者、廠商或製造商可以使用下列其中一種方法來解決這個錯誤。

執行智慧卡微驅動程式

我們建議智慧卡發行者、廠商和製造商執行智慧卡微驅動程式,並加入 Windows Logo Program,以享有平台所引進的改良功能,例如智慧卡隨插即用、智慧卡的裝置儲存等等。

如需有關 Windows 智慧卡微驅動程式規格的詳細資訊,請造訪下列 Microsoft 網站:如需有關如何開始為您的智慧卡微驅動程式取得標誌的程序,請造訪下列 Windows Logo Program 網站:

為您的智慧卡執行 NULL 驅動程式

如果必須有自訂式軟體 (如 PKCS#11 驅動程式、ActiveX 控制項或一些其他中介軟體) 才能在 Windows 中使用智慧卡,而且執行智慧卡微驅動程式或自訂式 CSP 不是可行的選項,我們建議卡片發行者、廠商或製造商考慮提交 NULL 驅動程式到 Windows Update。必須透過 Winqual 成功提交未分類的裝置,才能確保 Windows Update 有提供 NULL 驅動程式。如果未來這些卡片有可用的微驅動程式,新的驅動程式可透過加入 Windows Logo Program 上傳到 Windows Update。然後,使用者便可手動下載 NULL 驅動程式,或以選用的更新提供。

以下是智慧卡 NULL 驅動程式的範例範本。

透過受管理電腦的群組原則停用智慧卡隨插即用

這個選項僅建議用於企業部署,而該企業的電腦受系統管理員管理,且所有與企業正在使用之智慧卡搭配運作的必要軟體是透過使用軟體管理工具 (例如 SMS) 進行安裝的。

強烈建議您不要在下列環境中執行此程序,因為這麼做會影響您環境中的所有智慧卡:
  • 針對使用者的商務部署,例如線上銀行作業
  • 同時包含有隨插即用智慧卡和非隨插即用智慧卡的環境,因為該環境會利用群組原則停用智慧卡的隨插即用
若使用者的電腦是由像是群組原則的機制所管理,則智慧卡隨插即用會在企業中被完全停用。

如果您的部署僅使用非隨插即用智慧卡解決方案,則智慧卡隨插即用會被用戶端電腦上的本機系統管理員停用。停用智慧卡隨插即用可避免使用者下載智慧卡驅動程式 (也稱為智慧卡微驅動程式),也可避免智慧卡隨插即用出現提示。

若要停用本機群組原則中的智慧卡隨插即用,請依照下列步驟執行:
  1. 按一下 [開始],在 [搜尋程式及檔案] 方塊中,輸入 gpedit.msc,然後按下 ENTER。
  2. 在主控台樹狀目錄的 [電腦設定] 下方,按一下 [系統管理範本]
  3. 在詳細資料窗格中,連按兩下 [Windows 元件],再連按兩下 [智慧卡]
  4. 用滑鼠右鍵按一下 [啟用智慧卡隨插即用服務],然後按一下 [編輯]
  5. 按一下 [停用],然後按一下 [確定]

變更使用者的系統,停用特定卡片的智慧卡隨插即用

這是最不推薦的選項。您應該只在當卡片是舊版卡片,而且未來沒有執行智慧卡微驅動程式的計劃時,才使用這個選項。這個選項會要求已安裝在電腦上的現有軟體通知 Windows,告知系統已安裝自訂式 CSP,即使使用者系統不存在這樣的 CSP。一旦 Windows 判斷系統已安裝自訂式 CSP,Windows 便不會透過智慧卡隨插即用,嘗試下載和安裝驅動程式。也不會在「裝置管理員」中建立和看到智慧卡裝置的裝置節點。這個選項會對系統登錄造成下列變更:

子機碼:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards\<Smart card name>
子機碼登錄項目:
  • ATR=Hexadecimal DWORD:智慧卡的逗號分隔 ATR。
  • ATRMask= Hexadecimal DWORD:逗號分隔遮罩以套用至 ATR,不遮罩 ATR 中不重要的位元組。
  • Crypto Provider=String value:某個與您的智慧卡相關的字串。
例如:
子機碼:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards\Fabrikam ATM card
子機碼登錄項目:
  • ATR=Hexadecimal DWORD:3b,dc,13,00,40,3a,49,54,47,5f,4d,53,43,53,50,5f,56,32
  • ATRMask= Hexadecimal DWORD:ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff
  • Crypto Provider=String value:"Fabrikam ATM Dummy Provider"
若為 x64 位元的系統,下列子機碼必須進行相同的變更:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Cryptography\Calais\SmartCards


我們建議,您可以使用 WinSCard API 將這些變更引進系統,取代直接變更系統登錄。以下是範本程式碼範例,藉由建立將卡片相關聯到不存在的提供者的登錄項目,程式碼範例可以偵測智慧卡插入,然後停用特定卡片的智慧卡隨插即用。
