Severity: normal

Trying to access a Canon EOS 350D doesn't work if the
permissions are granted through a group:
	/dev/bus/usb# lsusb
	Bus 002 Device 003: ID 04a9:30ef Canon, Inc. EOS 350D (ptp)
	/dev/bus/usb# ls -la 002/
	insgesamt 0
	drwxr-xr-x 2 root root          80 18. Nov 14:40 .
	drwxr-xr-x 4 root root          80 18. Nov 13:30 ..
	crw-rw---- 1 root root    189, 128 18. Nov 13:30 001
	crw-rw-r-- 1 root plugdev 189, 130 18. Nov 14:41 003
Capturing via digikam gives an error.


After
	/dev/bus/usb/002# chmod 666 003
it works as normal ... although the group should suffice:
	$ id
	uid=1000(flip) gid=1000(flip) Gruppen=6(disk),20(dialout),24(cdrom),
	25(floppy),29(audio),44(video),46(plugdev),100(users),1000(flip)

Strangely the only process opening that is digikam:
	/dev/bus/usb/002# lsof /dev/bus/usb/002/003
	COMMAND  PID USER   FD   TYPE  DEVICE SIZE  NODE NAME
	digikam 7396 flip   23u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   25u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   27u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   29u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   31u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   33u   CHR 189,130      27197 /dev/bus/usb/002/003
	digikam 7396 flip   35u   CHR 189,130      27197 /dev/bus/usb/002/003
Which has the required access rights:
	/dev/bus/usb/002# grep Groups /proc/7396/status
	Groups: 6 20 24 25 29 44 46 100 1000
	/dev/bus/usb/002# grep plugdev /etc/group
	plugdev:x:46:flip...
