Missing user permissions for usb camera (via PTP)

User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:220.127.116.11) Gecko/20070718 Fedora/18.104.22.168-1.fc7 Firefox/22.214.171.124
Description of problem:
Before updating to kernel 126.96.36.199-27.fc7 connecting a usb camera that uses PTP (not mass storage type), actually Canon EOS 350D, enabled a normal user to access the camera with gphoto2 to import the images to the computer.
After updating to kernel 188.8.131.52-27.fc7 the camera is still recognized and Gnome's automatic action (gthumb-import %h) is triggered. But as normal user (as root it's working) using gthumb-import or digikam to import the images fails with the error message:
"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."
Tried to configure udev to change permissions for the coresponding usb device to have permission 0666. But it didn't help.
Booting into kernel 2.6.21-1.3228.fc7 fixes the problem, which makes me believe that the new kernel changes something here.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Login as normal user
2. Connect digital camera via usb (camera using PTP instead of mass storage access)
3. Turn on camera
4. Try to import images on camera with digikam or gthumb-import
In digikam: error, but no specified error message.
In gthumb-import: error message (s.above)
Import allowed for normal user, not only for root.
Is this related to bug id. 248916?
For me gtump-import is unable to connect to Canon Powershot A40 and same happens
with Gnomad2 / Zen Micro.
Both work OK with kernel-2.6.21-1.3228.fc7.
CONFIG_USB_DEVICE_CLASS set in FC-6 and F-7 kernel configs.
Will be in the next update, and should fix this bug.

Do we know the timeframe for this update?
Should be in updatest-testing Real Soon Now. The impatient can grab it straight out of koji:

Works for me with the new kernel. Thanks.
I don't know if this is the same bug I am seeing but here we go:
When I updated to 2.6.22-27 kernel every time I insert my usb memory stick it
only gets recognized normally as seen in /var/log/messages but it doesn't mount
the drive. Nautilus doesn't pop up a new window showing the content and it
doesn't appear mounted in 'df'. The new kernel 184.108.40.206-33.fc7 doesn't fix this
The funny thing is that inserting CDs or DVDs works fine and nautilus appears on
the screen showing the content.
If I reboot back to 2.6.21 kernel then everything works fine. My usb memory
stick gets mounted automatically.
The new kernel 220.127.116.11-33.fc7 has cured the PTP Camera problems, thanks.
Yes, problem is fixed with kernel 18.104.22.168-33.fc7.
Thanks for this immediate reaction. Great work!
Mmmm... may be the report I made in comment #8 is a different problem, should I
report it in a separate bug?
Can anyone confirm the problem I am seeing? I just plug in my Trascend 1GB USB
memory into the USB port and it doesn't get mounted, although it gets recognized.
Right now I am using the latest official updates as of today, this is the output
of uname -r: 22.214.171.124-33.fc7
I'll attach the kernel log when I plug my usb memory.

kernel log when I plug in my usb memory stick
After it gets recognized in the kernel log I check the output of df -h and it
doesn't show there:
[william@localhost ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
22G 14G 7.8G 64% /

Some extra information:
- If I boot back to a 2.6.21 kernel everything works fine.
- I can mount the usb driver with mount as root.
- I have tested this on both, my laptop and my desktop computer, same result.
Am I supposed to close the bug after verifying it?
First bug I submitted here... ;-)
I have the same issue with my Olympus C-370Z. However unlike the original
reportee, I am using Rawhide and this bug has been there for the last few weeks.
I can immediately recall having used the following kernels:
Seems like the fix has not been ported to the Rawhide kernel.

Screenshot of error dialog on Rawhide i386.
It was a mistake on my part. My camera does not work via PTP, but is detected as
a USB mass storage device.
Sorry for the noise, I am restoring this bug to CURRENTRELASE.
This has stopped working again - error message An error occurred in the
io-library ..>" is the same as before. Please can someone confirm that this bug
hasn't re-emerged... ?
Does /var/lib/hal/acl-list have an entry that looks something like:
/dev/bus/usb/004/006 u 500
(what I see for my PTP camera). Last time I had this problem, acl-list had been
corrupted (so I replaced it with an empty file and restarted haldaemon).
No entries for /dev/bus... in this file, so it must be something else.
