I did not look up all the code (hint: format it as code to improve readability). But I recognized that you print the error message using FormatMessage(). SetupAPI messages are a little bit special. To get the correct error message you must use the macro HRESULT_FROM_SETUPAPI() to pass error codes to FormatMessage().

See the Guidelines for Using SetupAPI[^]. It also mentions that querying buffer sizes fails with ERROR_INSUFFICIENT_BUFFER (I did not remember when answering first).
