As
philmoz owns one of these cameras and worked on the port, I think we can safely assumed there is no problem with CHDK.
So that leaves something you have done (or not done). And to figure that out, we will need a lot more information.
Please describe exactly what you have done to install CHDK. What size card, what format, partitioning ? Did you use STICK or some other method.? Are you loading CHDK with the firmware update method or SD Card lock autoboot?
Please also describe the steps you used to enable saving of RAW images. Did you notice an increase in the delay after each shot when RAW was enabled?
Finally, tell us how you tried to find the resulting image. What folders on the SD card did you look in? Did you put the card into a reader on your computer or did you try to use a USB cable? (Hint : using a USB cable won't work - the RAW images will be hidden. You need to use a card reader directly attached to your computer).
