[PLUG] Fwd: gphoto2 error

[Anthony Schlemmer]

This is not so in some cases. I access my Kodak DX4900 directly using 
"gphoto2" without using the USBdevfs support. I have found that KDE 
incorrectly assumes that all digital cameras require the usbdevfs 
through a "kioslave" for digital camera access and I get I/O errors 
because of it. It is true that some cameras are accessed through a USB 
filesystem but there are quite a few cameras that aren't as well. I 
believe in the case of a camera that is mounted using the USBdevfs that 
there is no need to use "gphoto2" at all since I assume the pictures 
would be accessed like any other mounted filesystem Linux supports 
using common file utilities like "ls", and "cp" to list and copy the 
files from the camera to another location.

You are correct about the use of the "hotplug" service so permissions 
can be set to allow non-root users access to a digital camera.
