Immediately enable ODBC tracing. On Windows, the ODBC Data Source Administrator has a "Tracing" tab that logs every call to a file. On Linux, set ODBCINI and ODBCSYSINI environment variables and check the log. Additionally, use a simple, universal test tool like isql (on Unix) or the pyodbc one-liner pyodbc.connect(conn_str) from a Python terminal. This isolates the problem: if the driver works from a command-line test but fails in your BI tool, the issue is the tool's configuration (bitness, permissions, or environment), not the driver itself.
