It was a forgettable match, as both sides failed to produce the kind of attacking football that was expected.
The visitors created the first chance in the second minute when Felix Obada sent in an in-swinging corner, but Mor Diouf send his header over the bar from six yards out.
Ayanda Dlamini had a half-chance at the other end in the 17th minute, but sent his shot wide.
Michael Morton found himself with space on the right side in the 30th minute, but failed to get a clean connection with the ball, and in the end his tame shot resulted in a comfortable save for Tapuwa Kapini.
The first chance after the break fell to Felix Obada when he outran the defenders to meet a long pass, but he hurried his left-footed shot which failed to trouble the Usuthu goalkeeper.
The best chance for the home side came in the 73rd minute when Bongani Mbele broke through on the right and found Ayanda Dlamini on the edge of the penalty area, but his fierce shot was parried away by an outstretched Walters.
Four minutes later Mbele played a defence-splitting pass to release Goodman Dlamini, but he delayed his shot and when he finally took a shot at goal it was deflected off Byrone Hendricks, allowing Walters to make a save.
The visitors then had their best chance at the other end in the 83rd minute when Morton beat his marker on the right side and found Kurt Lentjies just outside the box, but his thunderous shot was tipped over for a corner by Kapini.
United almost benefitted from the resulting corner with Mor Diouf striking the crossbar with a well-executed overheard kick.
Although the game started to come to life in the closing stages of the second half, it was too little too late, and both sides should be satisfied with a point.
