[Desktop-packages] [Bug 1863239] Re: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group
The attached patch would fix this bug. It adds two rules to skip printers. The second skips all kinds of printers by checking whether the standard interface of a printer is present in the USB device. The first skips HP printers, it is the same rule as HPLIP uses. I have added it because it covers a second interface, which is probably of some weird proprietary HP printer devices. For my printer the bug goes away with this patch, also with any one of the two rules commented out. I think one can assume that there is no printer available which doubles as a media player. ** Patch added: "69-libmtp.rules.patch" https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1863239/+attachment/5339056/+files/69-libmtp.rules.patch ** Tags added: patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libmtp in Ubuntu. https://bugs.launchpad.net/bugs/1863239 Title: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group Status in libmtp package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Invalid Status in systemd package in Ubuntu: Invalid Status in udev package in Ubuntu: Invalid Bug description: When testing HPLIP I found out that CUPS backends can access my printer only when they are running as root, when they are running as the special user lp, as it is usually the case, they cannot access the printer.

[Desktop-packages] [Bug 1863239] Re: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group
There was already a measure against wrongly identifying HP printers as media players, but it is a rather dirty workaround which does not work any more (therefore this bug). The rule in the end of 69-libmtp.rules checks the absence of the env variable libsane_matched and this variable is set for all HP printers by HPLIP. First, this rule fails miserably if HPLIP is not installed, and I cannot imagine that the libmtp package depends on HPLIP only to identify unsupported devices. Also the libmtp rules are applied for both "add" and "bind" actions, whereas the rules of HPLIP (56-hpmud.rules) are only applied for "add" and so the bug happens on a "bind" action, here the HPLIP rules do not set said env variable and so the libmtp rules probe the HP printers. One can theoretically work around this problem by mucking with the UDEV rules of HPLIP, but this is a REALLY DIRTY workaround, so please DO NOT add an hplip task to this bug report. In addition, HPLIP will not be installed by default any more in the not too far future, as prnting and scanning will get snapped. Also we want printer driver Snaps (Printer Applications) not to run as root if possible, so we need to be sure that USB printer device files always belong to the group "lp" for all printer manufacturers and without HPLIP. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libmtp in Ubuntu. https://bugs.launchpad.net/bugs/1863239 Title: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group Status in libmtp package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Invalid Status in systemd package in Ubuntu: Invalid Status in udev package in Ubuntu: Invalid Bug description: When testing HPLIP I found out that CUPS backends can access my printer only when they are running as root, when they are running as the special user lp, as it is usually the case, they cannot access the printer.

[Desktop-packages] [Bug 1863239] Re: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group
Now I tried to investigate from which UDEV rule the wrong setting comes
from. First I searched all UDEV rules for the word "audio":
till@till-x1yoga:~$ grep -l '\baudio\b' /*/udev/rules.d/*.rules
/lib/udev/rules.d/50-udev-default.rules
/lib/udev/rules.d/60-persistent-v4l.rules
/lib/udev/rules.d/69-libmtp.rules
/lib/udev/rules.d/70-uaccess.rules
/lib/udev/rules.d/90-pulseaudio.rules
till@till-x1yoga:~$
So I expect only one of these can be the culprit. Actually a 'GROUP="audio"'
setting exists only in
/lib/udev/rules.d/50-udev-default.rules
and
/lib/udev/rules.d/69-libmtp.rules
The former is probably no problem as it assigns this group only to
devices of 'SUBSYSTEM=="sound"" where the latter seems to be actually
the culprit.
First it includes some devices explicitly and then it lists thousands of
supported devices. In the end there is some rule for passing a wide
range of devices through an auto-probing:
-
# Autoprobe vendor-specific, communication and PTP devices
ENV{ID_MTP_DEVICE}!="1", ENV{MTP_NO_PROBE}!="1",
ENV{COLOR_MEASUREMENT_DEVICE}!="1", ENV{ID_GPHOTO}!="1",
ENV{libsane_matched}!="yes", ATTR{bDeviceClass}=="00|02|06|ef|ff",
PROGRAM="mtp-probe /sys$env{DEVPATH} $attr{busnum} $attr{devnum}", RESULT=="1",
SYMLINK+="libmtp-%k", MODE="660", GROUP="audio", ENV{ID_MTP_DEVICE}="1",
ENV{ID_MEDIA_PLAYER}="1"
-
And this auto-probing tests positive on my printer:
till@till-x1yoga:~$ /lib/udev/mtp-probe
/sys/devices/pci:00/:00:14.0/usb1/1-1 001 012
1
till@till-x1yoga:~$
The device path of the printer I have taken from the blob in the udevadm
output (attached to previous comment) which also contains
"ID_MEDIA_PLAYER=1". So mtp-probe identifies my printer as a media
player and assigns the device file to the "audio" group.
I assume that this happens to most or even all HP printers, so an
exclusion of only my device via Vendor and Product ID would not be the
correct solution.
Either mtp-probe needs to get fixed or before said rule in the end of
the 69-libmtp.rules file and after the lines explicitly identifying
media players from HP, there should be placed a line to exclude further
HP devices, like
--
...
# Exclude any further, not explicitly specified HP devices
ATTR{idVendor}=="03f0", GOTO="libmtp_rules_end"
# Autoprobe vendor-specific, communication and PTP devices
ENV{ID_MTP_DEVICE}!="1", ENV{MTP_NO_PROBE}!="1",
ENV{COLOR_MEASUREMENT_DEVICE}!="1", ENV{ID_GPHOTO}!="1",
ENV{libsane_matched}!="yes", ATTR{bDeviceClass}=="00|02|06|ef|ff",
PROGRAM="mtp-probe /sys$env{DEVPATH} $attr{busnum} $attr{devnum}", RESULT=="1",
SYMLINK+="libmtp-%k", MODE="660", GROUP="audio", ENV{ID_MTP_DEVICE}="1",
ENV{ID_MEDIA_PLAYER}="1"
LABEL="libmtp_rules_end"
