 |
|
Hi,
I own a Canon Ixus II digital camera. I can use this camera only as root, as normal user there is a problem detecting the camera:
/var/log/messages show the right stuff:
| Quote: | usb 2-1: new full speed USB device using uhci_hcd and address 3
usb 2-1: ep0 maxpacket = 32
usb 2-1: default language 0x0409
usb 2-1: new device strings: Mfr=1, Product=2, SerialNumber=0
usb 2-1: Product: Canon Digital Camera
usb 2-1: Manufacturer: Canon Inc.
usb 2-1: uevent
usb 2-1: configuration #1 chosen from 1 choice
usb 2-1: adding 2-1:1.0 (config #1, interface 0)
usb 2-1:1.0: uevent
drivers/usb/core/inode.c: creating file '003'
hub 2-0:1.0: state 7 ports 2 chg 0000 evt 0002 |
As root I can use gphoto2 for example:
| Quote: | gphoto2 -P
Detected a 'Canon:PowerShot S200'.
Downloading 'IMG_4470.JPG' from folder '/DCIM/144CANON'...
Receiving data... |------------------------------ \ 70.5% 1s |
But as normal user:

Hi,
I am sure you are right, before I have been using udev (it was devfs if I remeber correctly) it worked ...
My problem now is to find the correct device.
/var/log/message doesn't show it to me:

I can't see which device is used ...
I did an
twice an redirected the output in separate file. A diff showed me the following:
| Quote: | # diff /tmp/dev1 /tmp/dev2

Looking into the files I saw the differences:
| Quote: |
./bus/usb/002:

crw-r--r-- 1 root root 189, 128 Aug 18 08:53 001
crw-r--r-- 1 root root 189, 136 Aug 18 15:07 009

and
| Quote: |
./bus/usb/002:

crw-r--r-- 1 root root 189, 128 Aug 18 08:53 001
|
Looking inside /etc/udev/rules.d/50-udev.rules:
| Quote: |
# tty devices

I set all usb device to group "usb", but this didn't help.

Thanks Kabuto,
adding plugdev group solved the problem, so simple can it be if you know it ...
