I'm quite sure, these error messages will disappear and my camera will be usable in normal mode again (only for root ...) if I switch off hotplugging support in my kernel configuration.

Works for me. Disabled hotplugging and generic scsi in my kernel. And now I can use my S45 in normal mode with gphoto2. |

I just recompiled/upgraded the hotplug package and everything is working perfectly.
Hell, even my USB printer is able to print 100 consecutive pages now. It used to ALWAYS abort after 2 - 3. So my print jobs were always disected.

I just purchased a cannon A70. Too much contradictory information. Can someone summerize exacly what is required for gphoto2 to work. Right now it does not. I have 2.4 kernel but I will upgrade to 2.6 if that is better.
Hotplug do i need it ?
What usb options ?
What is this PTP mode on camera and how do I enable it ? |

Which version of hotplug is installed on your system?
I see:
| Code: | (delos) ~$ qpkg -I -v hotplug
sys-apps/hotplug-20040105 *

Just tried with a newer hotplug here -- was using hotplug-20030805-r3 (latest unmasked), now using hotplug-20040105. After doing etc-update and ensuring scripts were up to date, I tried again with gphoto, but had the exact same problem as before -- 'corrupted data' error, etc.
On the other hand, I note there are masked versions of gphoto2 newer than the one I'm using. So, another question for symbiote: not only what version of hotplug, but also what version of gphoto2/libgphoto2 are you using? |

By chance, I just noticed a 'hotplug' script in /etc/init.d. Don't know whether that's always been there, but it's not in my default runlevel, and I don't remember ever running it. In any case, thinking it might help, I ran it (no errors reported), and tried the camera again.
It didn't work, but gphoto took a bit longer than before (after "Detected a 'Canon:PowerShot S200'") to spit out an error ("Could not establish initial contact with camera ... Error (-102: 'Corrupted data')"). Then, with --debug, I tried gphoto again -- and to my surprise, it worked. The good news ends there, unfortunately: I haven't been able to get it to work again.
I tried again, with --debug --debug, and here's the relevant part of the output:

Again, in syslog:

Don't know if there's any useful info there, but the long and short of it: problems persist, whether /etc/init.d/hotplug is run or not. |

I got same error as you.
I upgraded to kernel 2.6.1 and reinstalled hotplug the masked version. I did not try to intstall masked version of gphoto2 |

I've now had time to try the masked versions of gphoto2/libgphoto2 -- but alas, no difference; the problem persists.
[added later] Not only that, I'm also trying to get a USB bluetooth dongle to work, and am getting "hci_cmd_task: hci0 command tx timeout" and "usb 4-2: control timeout on ep0in" errors in my logs.... I'm beginning to think it's time for me to try an earlier release of 2.6, which doesn't have the most recent USB changes.  |

Ok i seem to understand the problem better now !!!
If you go read the whole post carefully a pattern emerges.
Many people are having this error which is "*** Error (-102: 'Corrupted data') ***" and they are using a canon camera.
I have kernel 2.6 and others have that.
They upgraded hotplugs to latest masked version.
I have upgraded gphoto2 to maked version.
But the problem is still there.
Now you must be aware that there is thing called mode Picture transfer protocol (PTP)
Canon seems to go out of their way not to inform us that PTP exists (in A70 user manual its not even mentioned). In the software guied I found this line
| Quote: | | See PTP Mode leaflet if you are using a Powershot G3 , Powershot S45, Posershot S230 Digital Elph/Isux 3. In addition set the camera's transfer settings to [PTP] if you use the method to download with these models |
Ok so I dug up the green leaflet and it says :
| Quote: | | If you encouter any problems during image download, use the software applications bundled on the Canon Digital Camera Solution Disk to download images. |
and it forgets to tell us how to place camera in PTP mode.
Ok apperantly the A70 and newer canon cameral work in either modes depending on which protocol gphoto starts talking in. Anyone tell us how to get gphoto2 to initiate PTP ?

Yet another update: I've now tried with a kernel having hotplug disabled. The good news: my USB bluetooth dongle now seems to work. The bad news: I'm still getting 'corrupted data' errors with gphoto2.  |

My update.
I compiled hotplug support out of the kernel and the connection to my canon A70 works fine now. From what I read one will need to be root to access the usb device.
I have kernel 2.6.1 with usb device filesystem
gphoto2 2.1.3 |

That's what I forgot! Without hotplug in the kernel, my S200 works now, using gphoto2 as root. Thanks for the reminder. |

That's just premission issue. You can acces your camera as a normal user aswell. Just do:
| Code: | | # /usr/lib/libgphoto2/print-usb-usermap > /etc/hotplug/usb/usbcam.usermap |

Yes, but that assumes a person is using hotplug, and is exactly what I'd been enjoying with 2.4.x kernels. The only way we've been able to get gphoto2 to work at all with 2.6.x is by disabling hotplug altogether in the kernel, which precludes the hotplug way of managing device permissions. |

Yep! I can confirm that!
I also can confirm, that it is possible (at least with my Canpn A70) to use the camera in PTP mode if you want to use hotplugging support.
The camera discovers the protocol (either "normal" or "PTP") automagically by the way it gets initialized by gphoto2, digikam, ...
To enable the PTP protocol in digikam select the camera model Canon PowerShot A70 (PTP) in the camera setup dialog. When using gphoto2, start it with --camera="Canon PowerShot A70 (PTP)"
Hope, that helps a bit ...

can anyone confirm that support for the Digital IXUS/Powershot S200 is still broken? As far as I can tell, these models don't support PTP mode. If I'm mistaken, and some has gotten it to work for these models, please post details!
Thanks,

My S200 works now when I run gphoto2 as root, with a 2.6.1 kernel compiled from development-sources without hotplug support enabled. Not sure it matters, but I'm using the latest (still masked) versions of gphoto2 and libgphoto. As for PTP mode, I think you're right, it's not an option for the S200. |

As far as I can tell from this:
| Code: | (delos) ~$ gphoto2 --list-cameras | grep 'Canon.*PTP'
"Canon Digital IXUS 2 (PTP mode)"
"Canon Digital IXUS 400 (PTP mode)"
"Canon Digital IXUS v3 (PTP mode)"
"Canon EOS 300D (PTP mode)"
"Canon EOS Digital Rebel (PTP mode)"
"Canon EOS Kiss Digital (PTP mode)"
"Canon PowerShot A60 (PTP)"
"Canon PowerShot A70 (PTP)"
"Canon PowerShot A80 (PTP)"
"Canon PowerShot G3 (PTP mode)"
"Canon PowerShot G5 (PTP mode)"
"Canon PowerShot S230 (PTP mode)"
"Canon PowerShot S45 (PTP mode)"
(delos) ~$ |
the IXUS/PowerShot S200 is not supported in PTP mode by gphoto.

However, disabling hotplugging in the kernel resulted in PCMCIA support being taken out, too, which I need for my laptop. Sigh. Maybe a few mroe releases and all will be well. |

I haven't even tried to disable hotplug for the exact same reasons (wireless card), and nothing suggested on this post ever solved the problem (sometimes the camera would work for the first time, and give the same errors mentioned earlier on the subsequent times). However, I have been able to make it work again using linux-2.6.2-rc1 and linux-2.6.2-rc1-mm1. Gphoto2 works, and I am playing with S10sh, that even let's me do a thing I couldn't do with either gphoto2 or the Windows XP original drivers - file upload  |

I have a Canon PowerShot A40 and had the same "corrupt data" issues as above.
After some investigation of the hotplug scripts I unmerged usbutils to remove usbmodules. I can now connect with gphoto2 without problems with hotplug support compiled into the kernel.
I am running kernel 2.6.1mm4 with hotplug support and PCMCIA. |

Unmerging usbutils did the trick for me and my powershot S200.
Yet I don't know what usbutils does exactly!! 
Are there any programs that have usbutils in their dependencies??
And this seems to generate strange messages when booting. I get the following message on boot:
| Quote: | hub 1-0:1.0: new USB device on port 2, assigned address 2
usb 1-2: bulk timeout on ep1in
usbfs: USBDEVFS_BULK failed dev 2 ep 0x81 len 512 ret -110
usb 1-2: USB disconnect, address 2
|
And I get some kind of warning during the "starting hotplugging USB and PCI devices" part.
But well, as long as it works who cares  . Only if any of you know a bit more about that, just let me know. Thanks everyone. |

So, only libgphoto2, hotplug, and usbd list usbutils as a dependency, which means emerging or upgrading any of those will result in the re-emerging of usbutils.
On the other hand, the gphoto2 documentation includes neither hotplug nor usbutils among its requirements. My guess is that they're required by the ebuilds because, when they work, they do make things more convenient; in spite of that, since gphoto2 itself doesn't require it, it appears it's okay to use gphoto2 without usbutils (or hotplug, as we already knew). |
