No problem; it's OK that you read it now. :-) :-)

(I should note that this is on SUSE 10.0.)
puma:dev $ ll /dev/bus/usb/*/*
lrwxrwxrwx 1 root root 18 Jan 16 22:27 /dev/bus/usb/1/1 -> ../../../usbdev1.1
lrwxrwxrwx 1 root root 18 Jan 16 22:27 /dev/bus/usb/2/1 -> ../../../usbdev2.1
lrwxrwxrwx 1 root root 18 Jan 16 22:27 /dev/bus/usb/3/1 -> ../../../usbdev3.1
lrwxrwxrwx 1 root root 18 Jan 16 22:27 /dev/bus/usb/4/1 -> ../../../usbdev4.1
lrwxrwxrwx 1 root root 18 Jan 16 22:27 /dev/bus/usb/5/1 -> ../../../usbdev5.1
That's why I asked for the /dev/usbdev* devices. Anyhow, there are no user ACLs:
puma:dev $ getfacl /dev/bus/usb/1/1
getfacl: Removing leading '/' from absolute path names
# file: dev/bus/usb/1/1
# owner: root
# group: root
user::rw-
group::rw-
other::---
I'm using standard login on the console, btw., and /etc/pam.d/login
requires pam_resmgr.so for the session. resmgr works itself, as can be
seen by the access rights of my sound devices or my CD writer, where
the ACL for my userid schrod was added:
puma:dev $ getfacl /dev/sr1
getfacl: Removing leading '/' from absolute path names
# file: dev/sr1
# owner: root
# group: disk
user::rw-
user:schrod:rw-
group::r--
mask::rw-
other::---
"resmgr list usb" outputs "no devices available"
even though the lsusb output shows that there are some:
puma:~ # lsusb
Bus 4 Device 1: ID 0000:0000
Bus 5 Device 2: ID 04a9:3119 Canon, Inc.
Bus 5 Device 1: ID 0000:0000
Bus 1 Device 1: ID 0000:0000
Bus 3 Device 1: ID 0000:0000
Bus 2 Device 1: ID 0000:0000
That lsusb works only as root, though. As normal user, lsusb outputs
nothing, also no error message for the EACCESS it gets when it tries
to open /dev/bus/usb/*/*.
Sadly, hal-resmgr --list doesn't work, the option is not known (maybe
that option was added in a more current SUSE version).
lshal lists the USB devices, the attached camera, and also the Hub
Interface and the Host Controller. But it doesn't list any
resmgr.device entries for the latter; also no serial.device or
linux.device_file or some similar entry that has /dev/bus/usb/*/* as a
value. Maybe that points to the problem cause?
Sorry for the longer post, but I wanted to supply the information that's
available to me, to reduce email ping-pong. ;-)
It would be great if you could see anything that went wrong.
Hmm, a last question: Maybe it's sensible to add the usb device files
manually to the resmgr configuration? Something like
add /dev/bus/usb/1/1 desktop
for all USB device files?
Best, and thanks again for looking at my problem,
Joachim
