I've got an old film camera that uses a cable to connect to a PC. The camera records information like shutter speed, lens used, flash fired, focal length, etc. I'd like to download this information and keep it with my photos. The software that comes with this cable works only on Windows XP. I'm trying to get something that will work with a python script on linux ideally.
My first thought was to capture some usb/serial traffic and see what is sent and received. After several tries, I got some data captured. However, I can't really understand what is going on. It's rather cryptic to me.
List of Details:
- In Windows XP the device shows up as using com3/4, hence I think it is a serial device over USB. I couldn't get portmon to capture anything at all.
- I tried various USB sniffers inside windows xp virtual machine--none worked.
- I tried capturing USB traffic in VMWare logs, this worked but it's cryptic and doesn't look terribly helpful.
I was hoping to get a set of commands that are available on this device to send and receive various pieces of data. Are there any good suggestions/tips/tricks that you can offer to get me started down a successful path? I know this will be trial and error, but what else can I try? Maybe the data I have is sufficient and I need to interpret somehow?
Any suggestions are appreciated!
