I posted this to comp.os.linux.misc but the feedback I have got so
far is not very useful; maybe Slackware experts can do better.

I am running Slackware 10.2 with a 2.6.16.9 kernel. I have connected my
Canon Optura 20 to the USB ports on my Linux box, and the camera seems to
be recognized all right, as far as the USB interface is concerned. The
output from lsusb is

Bus 005 Device 002: ID 04a9:307f Canon, Inc. Optura 20 Bus 005 Device 001:

0000:0000
Bus 001 Device 001: ID 0000:0000

whereas that from cat /proc/bus/usb/devices is (I am including the
relevant portion only):

The output from gphoto2 --list-ports is

Devices found: 3
Path Description
--------------------------------------------------------------
usb:
Universal Serial Bus usb:005,002
Universal Serial Bus usb:002,002 Universal Serial Bus

However, gphoto2 --auto-detect fails to detect it. In fact, when invoked
with --debug it prints out lots of lines like

1.439791 gphoto2-port(0): Could not find USB device (vendor 0x2770,
product 0x9120). Make sure this device is connected to the computer.

One if the lines contains the vendor and product numbers for my camera,
as reported by lsusb above.

From all this I surmise that the kernel has recognized the camera all
right, but somehow gphoto2 (and flphoto - I tried with that as well) seem
to be unable to access it, be it as root or any other user.

What am I missing?

Try using digikam instead. You can either find the latest version, compile
and install that or go to http://linuxpackages.net and search for digikam.
It may well only recognize your camera as a PTP camera but it will still be
of use.

Thanks for your suggestion. The thing is, under Slackware 10.0 this
camera can be used under gphoto2 and flphoto without any problems. I am
guessing it must be a matter of configuring things correctly - but I am
stymied :-(

How did you install gphoto? 10.2 did not ship with GNOME so there is no
gphoto with the base install. My guess is there is a library missing or it
is not properly linked to the library needed for installation? When
starting from the command line do you have an error related to a certain
missing library?

It was installed by Freerock Gnome.

No:

$ ldd /usr/bin/gphoto2

linux-gate.so.1 => (0xffffe000)
libaa.so.1 => /usr/lib/libaa.so.1 (0xb7f94000)
libm.so.6 => /lib/tls/libm.so.6 (0xb7f51000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0xb7e87000)
libgpm.so.1 => /lib/libgpm.so.1 (0xb7e81000)

libdl.so.2 => /lib/tls/libdl.so.2 (0xb7ba9000)

gphoto2 is correctly installed, I believe. Also, remember that I also
tried with flphoto, with the same negative results.

i would guess that you have permissions problem. try using
gphoto-set-procperm (it should be included in libgphoto2), or try
searching on google for setting permissions for usb PTP cameras.
maybe you should first try running as root:
# gphoto2 --auto-detect
and if it finds camera, then it's definitely problem with permissions.

YOu're doing better than me. I coulnd't even get Gphoto to compile
under slack 10.1. May be mismstched libs. I may wait till I have
11.0 settled in.

I have no experience at all with Gphoto, and have not looked back to the
thread on comp.os.linux.misc to see if you've check this already, but in
case you haven't, does the following help at all?

http://www.gphoto.org/doc/manual/FAQ...d-not-find-usb

Hrmmm... if the auto-detect fails as root, the above may not be very
helpful. In that case, I would trace Gphoto (using "strace", and saving
the output to a file, because it's likely to be more than a little
copious ...), and look through that for any clues ...

> What am I missing?

I'm hoping the above link to the Gphoto FAQ will help fill in whatever
it is ...

Things do not change when running gphoto2 as root, as I mentioned.

Thanks. I looked into the document above and did as explained.
Unfortunately, the suggested remedy (setting USB permissions correctly) is
very poorly written, prompting as many questions as it answers. At any
rate, I think that my setup is fine, for I can use other USB devices with
no problem whatsoever.
