Camera not detected anymore [SOLVED]

since recently my camera "Canon PowerShot A95" isn't detected anymore.

the module ist loaded after connecting:
everything.log:
Mar 20 11:31:22 matrix usb 1-2: new full speed USB device using uhci_hcd and address 2

however, the camera doesn't appear:
lsusb:
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

There's no diffence when running as root
Any ideas ?

Actually, that log message doesn't say the module is loaded - it just says that the device has been detected and assigned a bus address. It should still show up on lsusb, though.

Is it USB Mass Storage or PTP?

Thanks for your responce.

Well, the camera was detected as PTP.

In addition, other usb devices work without any problems: eg printer, Palm and usb-stick and usb-harddrive

Re: Camera not detected anymore [SOLVED]

At PTP mode the camera isn't detected as a storage device.
You need something like gphoto or digikam to get its contents.
If the camera has a normal/usbstorage setting (I think not, as happens with most Canon digicams), then use that one instead before connecting it.

Re: Camera not detected anymore [SOLVED]

I ran:

gphoto2 --auto-detect

as user and as root
still, no camera detected

I've also installed Ubuntu on my second partition.  Here my camera was detected without any problems.

Again, a few weeks ago everything worked perfectly on ARCH.

Is there anyone out there who can help?

Re: Camera not detected anymore [SOLVED]

Hi,

I use a PowerShot A620, which shows up as a generic PTP camera. I had a brief problem (gtkam said something like: "unable to access /").  After a little head scratching, I found this was due to using an old version of /etc/udev/rules.d/gphoto.rules.  Once I copied the new gphoto.rules.pacnew over the existing gphoto.rules, I had to change the lines:

# USB PTP Class Camera
#SYSFS{idVendor}=="0000", SYSFS{idProduct}=="0000", GROUP="camera"

to read:

# USB PTP Class Camera
SYSFS{idVendor}=="0000", SYSFS{idProduct}=="0000", GROUP="camera"

After this I could access my camera again.

Maybe your problem is related?  Either way, I hope you manage to sort it out.

Regards,

Rob

Hmmm... I have no issues at all with a Cybershot DSC-P200 and the current stock kernel, with latest udev/dbus/hal/pmount versions (nothing from /testing). Factly, I can use the camera both at usbstorage and PtP mode.

Re: Camera not detected anymore [SOLVED]

Ups ...
.. I've noticed an older udev-rules I wrote for my Palm device that I didn't need anymore.  It seemed to conflict with my camera.  I don't know why it worked before. However, since I deleted the rules my camera is detected again.

Thanks to all
