Hi
This is very basic, but I could not find it in the FAQ.
I have an Olympus 2100 UZ sitting on my USB bus, and if I use GPhoto2
as root I can successfully download pictures from it. If I try as a
user, I get :
*** Error ***
An error occurred in the io-library ('Could not claim the USB device'):
Could not claim interface 0 (Operation not permitted). Make sure no
other program or kernel module (i.e. dc2xx) is using the device and you
have read/write access to the device.
*** Error ('Could not claim the USB device') ***
I have the following USB modules loaded:
/lib/modules/2.4.17/kernel/drivers/usb/hid.o
/lib/modules/2.4.17/kernel/drivers/usb/scanner.o
/lib/modules/2.4.17/kernel/drivers/usb/usbdnet.o
(basic USB support is compiled inot the kernel and so does not appear
as a module).
When I plug the camera in I get the following in the syslog:
Jul 17 08:26:27 gododdin kernel: usb.c: kusbd: /sbin/hotplug add 8

What do I need to do so that ordinary users (as opposed to just root)
can download pictures?
