Problem with Powershot A590 IS usb remote shutter

I recently installed CHDK on my two powershots A590 IS and I didn't experience any problems in doing so.  The problem started when I build the usb remote shutter release cable. 
I followed this tutorial to the letter:

I checked the cable thouroughly, I measured the voltages and the it is my understanding that the cable is okay.
Problem is that it doesn't work with my cameras. 
I changed the settings to 'remote control' but when I have OSD on there is a little menu that you can use when you press the shutter in to the first position (than using the arrow keys you can select various items).  So if I push the shutter on the camera everything is okay but when I push the switch on the usb cable, the camera doesn't even recognize this as a shutter press down.
Can anyone help me out?

That's a nice mostly correct video but if you want all the details of using a USB remote then this CHDK wikia page might be of more help : CHDK USB Remote

What you are seeing is normal.  While you can use the a "half press" of the shutter button to trigger certain CHDK functions, the USB remote will not do that.  It is only for actually taking a photograph. When CHDK is not in <ALT> mode and the camera is in shooting mode, closing the USB switch causes a picture to be taken (assuming you have correctly configured all the options in the configuration menu - see the wikia page linked above)

Yes, thank you for the info.  I solved my problem.  The settings needed some adjustement. :)
