From your description, the mostly likely problem is that the password
field of the user table is NOT a hashed password value. The authentication
attempt would fail because the database is trying to compare a hashed
password (coming from your ODBC driver) to a non-hashed value. Use the
PASSWORD() function to hash a plain-text password for the user so that it
will match the authentication attempt from the driver
update mysql.user set password = PASSWORD(`password`) WHERE user =
'odbclogin';

A second reason could be because the MySQL ODBC driver is acting as a
PRE-4.1 client (it is using the shorter password hashes that existed
before v4.1).
update mysql.user set password = OLD_PASSWORD('plaintext_of_password')
WHERE user = 'odbclogin';
