Description:
There are actually two problems here: one is that the currently-available version of the Windows ODBC driver (nominally 3.51.12) identifies itself internally like a Linux version, as "libmyodbc3.so".  The other (larger?) problem is that there was a prior version of myodbc3.dll, dated 6/1/2005, which is also externally identified as version 3.51.12, but which internally identifies itself (correctly, in my opinion) as "myodbc3.dll".  This is a problem because the nominal version string does not completely identify the version, and because the older version does not seem to be available any longer.

You can verify these differences using the Unix-style command "strings myodbc3.dll | grep odbc3".  I noticed the difference examining Microsoft.NET's System.Data.Odbc.OdbcConnection.Driver property.

How to repeat:
The 6/1/2005 version was downloaded last year sometime, apparently.  I downloaded the 10/15/2005 version today from the Hobbly mirror site in Chicago.

Suggested fix:
Don't put Unix-style strings in the Windows version, and make sure that every different version of the driver is identified uniquely!

Hi Jon. Thanks for your bug report.
Verified as described by reporter:
        string dsn = "Driver={MySQL ODBC 3.51 Driver}" +
                     ";Option=" + option +
                     ";Server=" + server +
                     ";Uid=" + userId +
                     ";Pwd=" + password +
                     ";Port=3307"+
                     ";Database=test";

        OdbcCommand ocmd = new OdbcCommand("use test");
        using (OdbcConnection oconn = new OdbcConnection(dsn))
        {
            ocmd.Connection = oconn;
            oconn.Open();
            ocmd.ExecuteNonQuery();
        }

Output:oconn.Driver	"libmyodbc3.so"	string

Bug has been fixed. This fix also solves the problem with query logging in debug version of MyODBC. Fix was sent to developers for review.

Fixed in 3.51.14. Added the proper library name in the code for WIN section.
