Thanks.
As cgansen has noticed I had forgotten to give my kernel version.
I run a freshly compiled gentoo-dev-sources 2.6.1.
Just to be very precise, my first gentoo installation was with a 2.4.20, and my powershot worked perfectly - almost everything ran perfectly, actually.
Then my box had a major crash and I had to reinstall everything (windows + linux). I installed a gentoo-sources 2.4.22 rc 8 or 9 and was very unhappy with it (BIG problems with sounds and multitasking....)
My new 2.6 kernel runs quite amazingly. Very fast and so far very stable. But I encounter more problems with my peripherals, especially usb!! |

Well finally it seems that unmerging usbutils is not a satisfactory solution.
It sort of gives acces to the camera, but when I want to save more than one image on my computer I get errors and finally just the first image is saved. If I try to "Save all" the program dies instantly.
Then when usbutils is unmerged I get a "can't sythetize root hub events" during the start of hotplug at boot. Don't really know what it means, but it doesn't look so good....... |

tristure, are you using the hotplug init script?
I haven't been using this script with the 2.6 kernel.
I have also remerged both libgphoto2 and hotplug without usbutils (after removing the dependancy in the ebuilds), both compiled successfully so it appears not to be required for either to function.
Not sure what the usb errrors are on boot as I don't get them. |

I just did an emerge hotplug then rc-add hotpluf default.
So I assume I use the init script.
How is it possible not to use it?? |

This will remove hotplug from your default runlevel, and prevent it from loading automatically at boot time:
| Code: | | rc-update del hotplug default |
Doing that and rebooting is likely the best thing to try, for a 'cleaner' start. You can also stop the hotplug service, if it's running, without rebooting:
| Code: | | /etc/init.d/hotplug stop |

Well, the thing is I do want to keep hotplug. I need it for my mp3 player (with which I have many problems too, there's a thread about it in this very forum  ).
Reading toberonenz's post I understood there was another way to have hotplug than to use the default script... And given the fact that I can't get the whole USB stuff to work correctly, and that I don't understand a friggin'damn thing about it, I was ready to try that solution too.
Oh by the way, while we're on the topic of canon powershot, have you noticed this? :
When I use it in Windows, all pictures are oriented correctly. I mean there is no need to rotate (90 or 270) the ones you shot in "portrait" position.
When using gtkam in linux the correction is not made. And I have to rotate the pictures manually. It's not too bad, but if there was an option to make it work, I would be glad to hear it 
Thanks everyone! |

This is because the camera does not actually rearange the pixels of the image it keeps them the same , it simply tags the jpeg in the exif header to specify the orientation. Sure canons own software is smart enough to figure it out but general purpose stuff like gtkam is not smart enough. |

Hi,
I've got a little pb with my Powershot S40
I compiled my kernel with the good options (I assume)
emerged gphoto2 and gtkam ...
When I plug my camera I have

but, I have no /proc/bus/usb
I don't know why, maybe one of the 2.6 kernel feature (sysfs) but I compiled procfs support ... so ?
What can I do ...
Well, I don't know why, I compiled USB File System support, and installed my new kernel but ... it seems it didn't work ... I'm recompiling and I will try again ...
they key seems to be there:

@Zidge
could you post the usb sections of your kernel .config?
Or make a link to your entire .config?
It could help if we want to check that you activated the right options. To me, /proc/bus/usb not existing sort of looks like something's mising in the kernel. (or you compiled things as modules that are not loaded right now)
@Everyone else
I've tried various things (in console.perms, devfsd.conf, etc...) and changed many permissions, tried to alter my hotplug configuration... And still I can't get any resultats without unmerging usbutils. It seems very strange.
OK, this is not a desperate situation as I can access my camera (but I have to log in as root), and the usbutils package is not really crucial.
Yet this is to me an "bad situation" (understand : situation really worse than what happens in windows ). I really would like to understand what the hell is going on.
Anyone got new hints about USB, digital cameras and usbutils package?
THanks! |

just as an update, I was able to get my Powershot S200 to work with the following:
Kernel: 2.6.1-mm5
hotplug: sys-apps/hotplug-20030805-r3
libgphoto2: media-libs/libgphoto2-2.1.3-r1
gphoto2: media-gfx/gphoto2-2.1.3
And no usbutils.
Hope this helps

it looks like your system has not "automagically" mounted the usb filesystem. It should be done at bootup, by one of the init scripts (Anyone feel free to point out the correct place, it'll be nice to really know!)
do a
and if you have it mounted the it will show a line similar to this
| Code: | | none 0 0 0 - /proc/bus/usb |
if you don't have it mounted try
| Code: | | mount none -t usbfs /proc/bus/usb |
or try
| Code: | | mount none -t usbdevfs /proc/bus/usb |
if it mounts sucessfully then
| Code: | | cat /proc/bus/usb/devices |
this will show you your usb controllers and devices if attached
otherwise I'm at a loss. |

another thought, you could try the following
| Code: | | sh /etc/hotplug/usb.rc status |
this will give you some useful info of your usb setup.
it give me

Yay! Kernel 2.6.2 fixed this problem for me!
gphoto2 runs just like it should - with no configuration changes to my previous setup.
Just hope I get my usb-bluetooth dongle working with this new kernel, too. |

Hi all.
I have the same problem on my 2.6.2-ck1.
I tried upgrading libgphoto2, gphoto2 and hotplug.
I also tried to disable hotplug, thou I still have support for it in the kernel.
My camera is a canon coolpix 880, --auto-detect finds the camera, but when trying to browse/download I get the same error as everyone else.
Any other suggestions?

Just FYI. Actutally usbutils is not required per se by gphoto2. It actually uses libusb. There was a conflict between usbutils and libusb using the same library name and that was fixed in an upgrade usbutils ebuild so it actually is checking to make sure you have that. Most likely you could just re-emerge libusb without removing usbutils and it would work also.
Btw. You can build just the gphoto drivers your want with the GPHOTO_LIBS environment variable seperated by comments or add to make.conf. Here is the comments I added to the ebuild.
# If you want to only compile for specific camera(s), set GPHOTO_LIBS
# environment to a comma-separated list (no spaces) of drivers that
# you want to build.
#
# For example:
#
# env GPHOTO_LIBS='canon,ptp2' emerge libgphoto2
#
# drivers: agfa-cl20, barbie, canon, casio, digita, dimera,
# directory, fuji, gsmart300, jamcam,
# jd11, kodak, konica, mustek, largan,
# minolta, panasonic, pccam300, pccam600,
# polaroid, ptp2, ricoh, samsung, smal,
# sierra, sipix, sonydscf1, sonydscf55,
# soundvision, spca50x, sq905, stv0680, sx330z |

Upgraded to 2.6.3. remerged both usbutils and libusb. upgraded libgphoto but still the same annoying problem.

I've upgraded all my computers to 2.6 with ntpl so theres no way back to 2.4 
Any other suggestion are very appreciated.
Thanx
