[gentoo-user] gtkam+non-rootuser
I'm trying to download my pictures from the digital camera but I can't
seem to succeed I get Could not list folders in '/'.
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 (such as sdc2xx, stv680, spca50x) is
using the device and you have read/write access to the device. from
gtkam although i have ivman hal started. I get no error when i try
to download as root though. I thought i could import direct them with
sudo gtkam but i get (gtkam:11668): Gtk-WARNING **: cannot open
display: so in visudo i uncomment the line
Defaults:%wheel !env_reset and Defaults:%users
env_keep=DISPLAY but when i get to save i get sudoers file: syntax
error, line 19 sudoers file: syntax error, line 22 any ideeas? I would
really like to get digital cameras working without logging root, also
writting a udev rule for a specific camera it's a bad ideea since all
my frinds have different models. Thanks in advance

Both my wife and I use gtkam on my PC at home, both as normal users with no setuid programs or sudo. I am not at home at the moment but iirc what I had to do was: in /etc/fstab: none /proc/bus/usb usbfs user,auto,devmode=0660,devgid=85 0 0 and in user's groups add plugdev I *think* that was all there was to it.

When you plug in your camera into your USB, what does `lsusb` show? Here: beast ~ # lsusb Bus 005 Device 001: ID : Bus 004 Device 001: ID : Bus 003 Device 010: ID 04a9:3055 Canon, Inc. PowerShot G2 Bus 003 Device 001: ID : Bus 002 Device 003: ID 046d:c00b Logitech, Inc. MouseMan Wheel Bus 002 Device 001: ID : Bus 001 Device 001: ID : Then, looking in /proc/bus/usb/[Bus-id_of_your_camera] beast ~ # ll /proc/bus/usb/003/ total 0 - -rw-rw 1 root usb 43 Jun 23 08:39 001 - -rw-rw 1 root plugdev 57 Jun 23 18:32 010 You see, the new device created here is the root:pludged one. What does yours show? The thing you need to keep in mind here is that you have to have rw permissions to that new device file, else you get that error. If yours is roor:root or something, do a chown of it and then try as user... the chances are it'll work (until you next plug your camera is of course). Doing a grep for plugdev in /etc returns /etc/hotplug/usb/usbcam ... seems that file is responsible for the permissions, but what happens then is a mystery to me ;-) As for that line being mandatory, no I don't believe so, but about 1 year ago I had the same issues, got talking with some usb-gurus and they said to add that. At that time it did the trick, and since then I've kept it ;-) Greetings, Ralph -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.2.2 (GNU/Linux) iD8DBQFEnBnLCt0ZF9kLPvYRAlxvAJ4uPDxfpIgH8XNx7zItpTYA1mBGdACfe7WY h35yYDMAsDN8pn8cgntDU1w= =2Wk9 -END PGP SIGNATURE- -- gentoo-user@gentoo.org mailing list

If yours is roor:root or something, do a chown of it and then try as user... the chances are it'll work (until you next plug your camera is of course). Searching the net also found this: Like most, my camera identifies itself as an external hard disk connected over the USB bus, using the SCSI transport. To access my photos, I mount the drive and copy the image files onto my hard disk. Not all cameras work in this way: some of them use a non-storage protocol such as cameras supported by gphoto2. In the gphoto case, you do not want to be writing rules for your device, as is it controlled purely through userspace (rather than a specific kernel driver). here :http://www.reactivated.net/writing_udev_rules.html Doing a grep for plugdev in /etc returns /etc/hotplug/usb/usbcam ... seems that file is responsible for the permissions, but what happens then is a mystery to me ;-) Followed the instructions there but i got lost quickly as there were unclear to me so i did not got the script to do something useful As for that line being mandatory, no I don't believe so, but about 1 year ago I had the same issues, got talking with some usb-gurus and they said to add that. At that time it did the trick, and since then I've kept it ;-) I should also buy them a beer for a good advice here Thanks! -- gentoo-user@gentoo.org mailing list
