Cannot access images with gphoto2 from Kodak EZ200 #502

Describe the bug

I'm having issues with accessing camera images from my (very old) Kodak EZ200. I receive the error message: 

*** Error ***              
An error occurred in the io-library ('Error updating the port settings'): Could not release interface 1 (Device or resource busy).
*** Error (-37: 'Error updating the port settings') **

Name the camera Kodak EZ200
