I did as you describe and it did create  
/etc/udev/rules.d/90-libgphoto2.rules.

However I borrowed the camera from my grandson and don't have it to test 
with now. 

I was panicing because I wanted the photo of the VIN on a car I need to 
register and ran out of time to do that yesterday.  My daughter 
extracted the files on her Mac this morning and I made the desired copies.

So it's a non-problem until the next time.

By the way I should have mentioned this computer runs F-7.

Thanks for the help.
