ASP Classic: Problem with DSN-less Connection to MySQL

I'm trying to connect ASP classic to MySQL, running on localhost. Here's my setup:
  -  ASP is on XP Pro IIS 5.1 at port 1080 (localhost:1080)
  -  The MySQL server is part of WAMP at port 80.
  -  Installed the MySQL ODBC 3.51 Driver
  -  Although I'm trying to use a DNS-less connection, I have set up a System DSN named "MySQL" using the MySQL ODBC 3.51 Driver.  The parameters are: localhost, root, (no password), and the database name "mydata".
  - Tested the User DSN, and it connects OK.
  - Restarted computer, rechecked DSN; connects fine to the database "mydata" to be sure everything works.

    The ASP page runs fine as a "hello world" script (localhost:1080/helloworld.asp).  
   
   However, it gives an error message when I add the database connection string for a DSN-less connection.

----------------------
Update:  I just got it to work with this:

<%
Dim oConn, rs, sql
    Set oConn = Server.CreateObject("ADODB.Connection")
    oConn.Open "DRIVER={MySQL ODBC 3.51 Driver};" & _
                 "SERVER=localhost;" & _
                 "DATABASE=mydata;" & _
                 "USER=root;" & _
                 "PASSWORD=;"
[etc.]
%>

   and also with:

<%
Dim oConn, rs, sql
    Set cn = Server.CreateObject("ADODB.Connection")
    cn.Open "DRIVER={MySQL ODBC 3.51 Driver};" & _
                 "SERVER=localhost;" & _
                 "DATABASE=mydata;" & _
                 "USER=root;" & _
                 "PASSWORD=;"

   and also with:

<%
Dim cn, rs, sql
Set cn = Server.CreateObject("ADODB.Connection")
cn.Open "DRIVER={MySQL ODBC 3.51 Driver};" & _
                 "Server=localhost;" & _
                 "Port=3306;" & _
                 "Option=16384;" & _
                 "Stmt=;" & _
                 "Database=mydata;" & _
                 "Uid=root;" & _
                 "Pwd=;"

I also tried a remote connection, to a MySQL server out on the Internet, and it worked like this when calling the script from localhost:1080 :

oConn.Open "Driver={MySQL ODBC 3.51 Driver};" & _
           "Server=db1.mydatabaseserver.com;" & _
           "Port=3306;" & _
           "Option=131072;" & _
           "Stmt=;" & _
           "Database=mydata;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"


But it won't work on my ISP server
   What if the ASP script is hosted on a Windows ISP server where I do not have access to installing the MySQL ODBC Driver nor a DSN?  Is there any other way to connect?
     The error I'm getting, when trying to use the script on an ISP server, is:

Microsoft-IIS/5.0
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
