Comment 1 nucleo 2013-10-16 14:13:26 UTC 
Running "udevadm hwdb --update" as root after updating to sane-backends-1.0.24-1 not fixed problem, "scanimage -L" still detects scanner only if run it as root.

Comment 3 Nils Philippsen 2013-10-22 15:36:02 UTC 
Harald, I'll Cc you to this bug because of your issues you found when testing this update:

https://admin.fedoraproject.org/updates/FEDORA-2013-19260/sane-backends-1.0.24-2.fc19

I have done some tests here and apparently running 'udevadm hwdb --update' doesn't completely bring udevd up to date with regard to its rules and hardware database (at least not persistently). When digging into how udevd sees things ("udevadm info --name=...", "udevadm hwdb --test=...") I've seen libsane_matched=yes labels appearing and disappearing again until I kicked udevd hard with 'udevadm control --reload'.

Nucleo and Harald, since installing the sane-backends update, have you rebooted the machines to which your scanners are attached? If not, can you try 'udevadm control --reload' and either 'udevadm trigger --subsystem-match=usb' or disconnect/reconnect the device? Thanks.
Comment 4 nucleo 2013-10-22 15:41:07 UTC 
I rebooted system after updating sane-backebds, then powered on scanner, then 'scanimage -L' runned from usual user showed only webcam device.
Comment 5 Nils Philippsen 2013-10-23 13:40:58 UTC 
All, please try the following (and adapt paths, names, accordingly):

1) identify your scanner device in lsusb, the one I'm testing (and I know that it's driver by libsane-hpaio, not sane-backends ;-)) with looks like this:

...
Bus 001 Device 021: ID 03f0:2805 Hewlett-Packard
...

2) Write what udevd knows about the device to a file:

udevadm info --name=bus/usb/001/021 | tee udevadm-info-"$(hostname)".1.out

The result looks about like this:

P: /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1
N: bus/usb/001/021
E: BUSNUM=001
E: DEVNAME=/dev/bus/usb/001/021
E: DEVNUM=021
E: DEVPATH=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1
E: DEVTYPE=usb_device
...

3) Find the corresponding modalias of the device (using the info in P: above).

find /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1 -name modalias

--> /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1/1-1.5.1:1.0/modalias

cat /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5.1/1-1.5.1:1.0/modalias

--> usb:v03F0p2805d0100dc00dsc00dp00icFFisc00ipFFin00

4) Find out what hwdb thinks of this:

udevadm hwdb --test=usb:v03F0p2805d0100dc00dsc00dp00icFFisc00ipFFin00

That should give a result like this:

ID_VENDOR_FROM_DATABASE=Hewlett-Packard
libsane_matched=yes

5) Step 2) once more (to find out whether you have the same symptoms with udev hwdb that I had):

udevadm info --name=bus/usb/001/021 | tee udevadm-info-"$(hostname)".2.out

6) Attach both udevadm-info-"$(hostname)".1.out and udevadm-info-"$(hostname)".2.out to this bug.

Thanks!

Comment 8 Fabrice Bellet 2013-10-23 15:15:06 UTC 
Hi! It seems strange to me, but there may be a bug in the script that generated the file /usr/lib/udev/hwdb.d/20-sane-backends.hwdb, because all entries seem to have duplicated the vendorid into the productid :

[root@helix ~]# egrep ^usb /usr/lib/udev/hwdb.d/20-sane-backends.hwdb | head -10
usb:v03F0p03F0*

[root@helix ~]# rpm -qf /usr/lib/udev/hwdb.d/20-sane-backends.hwdb
sane-backends-1.0.24-2.fc20.x86_64
[root@helix ~]# rpm -V sane-backends
[root@helix ~]# 

Creating a local entry in /etc/udev/hwdb.d/20-local.hwdb just for my scanner with the correct string works for me : udevadm hwdb --test=xxx now displays the "libsane_matched=yes" line, the device /dev/bus/usb/yyy/zzz has the right acl, and sane-find-scanner finds it as a regular user.

Good catch, thanks! I'll look into that.
Comment 10 Harald Reindl 2013-10-23 19:59:25 UTC 
thank you for CC

yes i rebooted the machine multiple times because i tend to be an early-kernel-tester, often directly after a new release finished it's build on koji

xsane currently tends to start without device selection and select the Logitech webcam, the Canon scanner worked for years and in fact it would be nice finally not ask for the device and ignore the webcam at all :-)

Comment 11 Nils Philippsen 2013-10-24 12:39:30 UTC 
Fabrice, thanks for spotting this oddity. The sane-desc program which generated the hwdb file really did write the vendor ID twice. I'll build a fixed package shortly.
Comment 12 Nils Philippsen 2013-10-24 12:49:56 UTC 
I've proposed this bug as an F20 beta blocker because both a) the new minor release (1.0.24 -- 1.0.23 is missing lots of bug fixes) and b) using hwdb instead of humongous udev rule sets for permission setting needs to be tested by a wide audience.

Comment 18 Nils Philippsen 2013-10-28 10:43:59 UTC 
All: to test this, you may need to "udevadm control --reload" or even restart your machine due to a bug in current udevd which spoils picking up the new rules.
Comment 19 Nils Philippsen 2013-10-28 10:51:27 UTC 
NB: I've seen the fix for udevd in dist-git, it should eventually be available with systemd 204-18 or thereabouts.
Comment 20 nucleo 2013-10-28 11:09:31 UTC 
For me scanner works immediately after sane-backends update without any additional actions. After reboot it also works.
Comment 21 Mike Ruckman 2013-10-28 17:16:35 UTC 
Discussed in 2013-10-28 Blocker Review meeting [1]. Voted as an RejectedFreezeException. This seems unlikely to affect liveimage users and thus, could be fixed by a 0-day update.

Comment 22 Nils Philippsen 2013-10-29 10:00:48 UTC 
Harald, you've given negative karma to this update, but it seems to me you're suffering from the udevd issue that it's not picking up hwdb changes properly. Did you "udevadm control --reload" or restart your system after applying the update?
