As per the docs "usage" is not a privilege on a schema.
I believe the one you were looking for is CONNECT.
Revoking this bans a user from any access to the database, granting it
allows them to login to the DB (if their role is a LOGIN role) but on
it's own grant's nothing else.  They must also have usage on the
schema(s) etc.

http://www.postgresql.org/docs/current/static/sql-grant.html

GRANT { { CREATE | CONNECT | TEMPORARY | TEMP } [, ...] | ALL [
PRIVILEGES ] }
    ON DATABASE database_name [, ...]
    TO { [ GROUP ] role_name | PUBLIC } [, ...] [ WITH GRANT OPTION ]
