I/O Problem with Canon EOS 5DS

Karsh Sinha

I'm running a python script (on Ubuntu 14.04) that uses gphoto2 to fire 2 Canon EOS 5DS simultaneously and then save the picture on the computer.  It seems to work well for a minute or so, but then I get a error: [-7] I/O problem from both cameras when issues the capture command (gp.check_result(gp.gp_camera_capture(self.camera, gp.GP_CAPTURE_IMAGE, self.context))).  Has anyone else also encountered I/O problems with EOS 5DS?  Fyi, I'm using 2 USB 3.0 micro cable plugged into a usb 3.0 powered hub.
