My ODBC Configuration:
DSN name is :db

But, it is giving the following error.
ORA-03121: no interface driver connected - function not performed
Database version : 9.2.0.1.0
Operating System : Microsoft Windows XP
ODBC Version : 2.575.1117.00
I am trying to connect with the database like this:

As already stated, you can not use the DSN in SQL*Plus (nor TOAD, afaik)!
I can reproduce the error message with the following:
C:\>sqlplus a/b@ODBC:c
SQL*Plus: Release 11.1.0.6.0 - Production on Mon Aug 4 21:34:58 2008

ERROR:
ORA-03121: no interface driver connected - function not performedLooking up the message, it says:
Cause: A SQL*Net version 1 prefix was erroneously used in the connect string
Looks like this has nothing to do with your DSN - it is more a matter of not using a proper connection string.
If 'Test Connection' works then you should probably proceed to work with Crystal Reports, using the DSN in question.
However, you should note that the old MS ODBC driver for Oracle was designed for OCI 7 (and for databases 7.x-8.x) and is now considered obsolete by both MS and Oracle.
Deprecated MDAC components and MS KB Article 244661.
Use the Oracle ODBC driver included with a supported Client version instead.
Edit:
Clarifying and adding references.
