我在 Win10 操作系统上使用指纹模块开发 WBDI 和 EngineAdapter 时遇到了问题。
问题是为什么在我完成下面的第 1 步和第 2 步之后，EngineAdapter 没有进入下面的回调函数？
因为微软的文件提到，当注册工作流程通过时，将调用以下函数。( https://docs.microsoft.com/zh-tw/windows/win32/secbiomet/adapter-workflow )
以下是未调用的回调函数。
(1) “EngineAdapterCreateEnrollment” (2) “EngineAdapterSetEnrollmentParameters”
有谁知道如何解决它？非常感谢。
