How to connect to MSaccess with sqlplus provided in oracle11g

Question

With an old sqlplus (version 3.3.4) I was able to connect successfully to MSAccess database using these parameters:  
          SQLPLUS username/password@odbc:myDSNtoMSAccess
When using sqlplus provided in oracle11g (version 11.2.0.1) with the same parameters, I have this error message:
          ORA - 03121 : no interface driver connected - function not performed
Can someone can help me?
Thank you

Sorry for taking so long to answer you, I'm back to work.
Thank you all of you for your responses. Let me explain the situation:
We develop software that need to store data in diffenrent kind of database. Most common one used by our client are MSAccess, SqlServer and Oracle. One of our client is forced to upgrade their Oracle 8i database to 11g. This client received a lot of small MSAccess database from their clients and after the validation of the MSAccess data, copy their content into Oracle. With Oracle8i and SQLPlus 3.3.4 we develop a SQL script to copy the data. The client need to login to is Oracle database using SQLPlus and run a script file that contain the following SQL procedure:
    COPY FROM username/pw@odbc:myDSNtoMSAccess INSERT tablename USING select * from tablename;
We develop an application that do the same job and much more, but the client is an old fashion guy who only beleive in SQLPlus tools. Given that «the customer is always right», we recreate their Oracle environement with a server on which we installed the Oracle 11g database and a workstation on which we installed the Oracle client. We import successfully the dump file create with Oracle8i, and try some SQL request from the workstation with SQLPlus successfully. Our softwares were adjusted, recompiled and test successfully with Oracle 11g. The only thing that doesn't work is the login to MSAccess with SQLPlus. I think that Justin Cave is right «If memory serves, the ability to use SQL*Plus to connect to ODBC data sources was removed a long, long time ago». After some search and reading, the closest solution would be to use the Oracle gateway but it will be difficult to the client to use it because they will have to rename the MSAccess database and copy it on the specific path create with the ODBC on the Oracle server. This can be done easily, but different MSAccess database has to be validate and copy into Oracle by different user and this can happen in the same moment. So the gateway is not the solution.
To be honest with you, we are not disappointed. The client will not have the choice to drop SQLPlus and use our application!!!
Thank again to all of you and please excuse my english.
