@microfunguy - Thank you for the information.. I followed your post and looked at those pinouts, and also the cables that come with this specific camera (the SX130is). I will be building this cable soon, and will attatch all schematics if/when it works. The following is just for information: The USB cable is a standard USB 2.0 A male to Micro-USB B Male (it uses the "top" 5 pins in a row, 1=+5v (red), 2=Data-(white), 3=Data+(green), X=identifier, 4=GND (black). I didn't disasssemble the cable, but the camera (and CHDK) works with other standard cables, so I'm pretty sure the X pin isn't used for anything. The Video cable is NOT an HDMI cable. It is a special USB to RCA Video and Audio. There isn't really "data" coming out of those pins.. just analog video and audio signals. It uses the "bottom" half of the USB connector for this, and has no pins for the "top" half (so - I THINK - as far as the computer can see the camera is only connected to it.). I will be trying to find an "enhanced mini-USB" cable of any kind so I can re-wire it. here is the pinout for that one.
http://pinouts.ru/CellularPhones-A-N/emu_connector_pinout.shtml Notice pins 7-11 correspond to pins 1-4 on a standard mini USB cable, so I would only have to connect pins 1-6 to the video/audio RCA cables. If I can find one of these cables, I'll let you know if it works in a few days.
Here is the pinout for the cable/connector I will build.
