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.
