First off, I noticed that when I execute "gphoto2" it is running from 2.1.0 version. After doing make and make install of version 2.1.6, where is the executable of gphoto2 installed that I can run from that version? Maybe if I run with the 2.1.6 version, this will finally work.
Secondly, I noticed the debug line, 2.193950 gphoto2-camera(2): Initializing camera... 2.194862 gphoto2-port(0): The supplied vendor or product id (0x0,0x0) is not valid. 2.195469 context(0): An error occurred in the io-library ('Bad parameters'): The supplied vendor or product id (0x0,0x0) is not valid. But perhaps this is happening because I'm not running against version 2.1.6? Thirdly, just for giggles, I copied the new, /usr/local/lib/gphoto2/2.1.6/libgphoto2_polaroid_pdc640.so to, /usr/lib/gphoto2/2.1.0/ but that didn't work either. So I ran it debug mode and here is the debug output. Thanks for any ideas on this.
