The short hard plastic tube with the valve on the end is a bottling device...you will only use it to fill your bottles...it works great.
To siphon from you primary to the carboy, or from carboy to carboy just use the long hard plastic tube with the soft rubber tube....you'll have to start a siphon either by sucking on the end of the soft tube...or... some people use a new sanitized turkey baster [I have yet to try that method]
I have an auto-siphon like the one that Masta Posted in a previous photo...mine must be defective or operator error...I haven't tried it since I got the plastic topper.
Here is a photo of racking from the carboy back into the primary bucket when we were ready to bottle..
I cannot think how anyone could have trouble getting a auto siphon going, put it into the carboy, pump it a couple times, it's going. Maybe you had a defective one?

I had a hard time using my auto siphon for the first several tries. I finally had to use bread ties to tie the tube to the hard part of the siphon. It leaked air so much that it wouldn't siphon. Now I use the bread ties or plastic coated wire but I have to be careful I don't crack the hard tubing.
