--- Begin Message ---Package: cups Version: 1.5.2-9 Severity: normal Dear Maintainer, *** Please consider answering these questions, where appropriate *** * What led up to the situation? I was installing HP LaserKet P1006 printer using CUPS and printer-driver-foo2zjs (version 20120223dfsg0-1). After installation, my printer didn't work and my /var/log/messages was full of messages: -------------------------------- /var/log/messages BEGIN Mar 30 21:54:34 jbs kernel: [ 165.508737] usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x03F0 pid 0x3E17 Mar 30 21:54:34 jbs /etc/hotplug/usb/hpljP1006: foo2zjs: usb://HP/LaserJet%20P1006?serial=AA0309W... download failed.

Loads firmware into device file (function load_usblp(), line 218) in background 2. Loads same firmware into CUPS USB device (function load_cups(), line 238), also in background. It runs /usr/lib/cups/backend/usb to get the list of printers used in CUPS (as I get it) to put firmware in all of them. But it appears that /usr/lib/cups/backend/usb REMOVES usblp driver so removes device file. This causes loading firmware into device file to fail (well, driver unloads in progress of firmware loading) so printer doesn't work without proper firmware. Driver then loads back by hotplug or udev (I didn't digging this and it doesn't seem matter here) and that very script is loaded again causing flooding /var/log/messages with error messages. I made a hotfix for my system by removing '&'s (i.e. making it working in foreground) in /usr/sbin/hpljP1006; The result is that driver is reloading once in 3 seconds (cause /usr/sbin/hpljP1006 has ``sleep 3'' in it) and printer is highly unstable; but it's muich better that not working printer at all. Proper solution I believe is make /usr/lib/cups/backend/usb to NOT reload usblp. I might dig into CUPS code if needed. Another way to achieve correct result is to rewrite /usr/sbin/hpljP1006 script of printer-driver-foo2zjs package to catch driver reloading by calling /usr/lib/cups/backend/usb so maybe it should be passed to printer-driver-foo2zjs's maintainer. -- System Information: Debian Release: 6.0.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 3.2.0-2-686-pae (SMP w/1 CPU core) Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages cups depends on: ii adduser 3.112+nmu2 ii bc 1.06.95-2 ii cups-client 1.5.2-9 ii cups-common 1.5.2-8 ii cups-filters 1.0.11-1 ii cups-ppdc 1.5.2-9 ii debconf [debconf-2.0] 1.5.36.1 ii dpkg 1.15.8.12 ii ghostscript 9.05~dfsg-4 ii libavahi-client3 0.6.27-2+squeeze1 ii libavahi-common3 0.6.27-2+squeeze1 ii libc6 2.13-27 ii libcups2 1.5.2-8 ii libcupscgi1 1.5.2-9 ii libcupsimage2 1.5.2-8 ii libcupsmime1 1.5.2-9 ii libcupsppdc1 1.5.2-9 ii libdbus-1-3 1.2.24-4+squeeze1 ii libgcc1 1:4.7.0-1 ii libgnutls26 2.12.18-1 ii libgssapi-krb5-2 1.10+dfsg~beta1-2 ii libkrb5-3 1.10+dfsg~beta1-2 ii libldap-2.4-2 2.4.23-7.2 ii libpam0g 1.1.1-6.1+squeeze1 ii libpaper1 1.1.24+nmu1 ii libslp1 1.2.1-9 ii libstdc++6 4.7.0-1 ii libusb-1.0-0 2:1.0.9~rc3-3 ii lsb-base 3.2-23.2squeeze1 ii poppler-utils 0.16.7-3 ii procps 1:3.2.8-9 ii ssl-cert 1.0.28 Versions of packages cups recommends: ii avahi-daemon 0.6.31-1 ii colord 0.1.18-1 ii foomatic-filters 4.0.15-1 ii ghostscript-cups 9.05~dfsg-4 ii printer-driver-gutenprint 5.2.7-5 Versions of packages cups suggests: ii cups-bsd <none> ii cups-pdf <none> ii foomatic-db-compressed-ppds [foomatic-db] 20120322-1 ii hplip <none> ii printer-driver-hpcups <none> ii smbclient 2:3.5.6~dfsg-3squeeze6 ii udev 175-3.1 -- Configuration Files: /etc/cups/cupsd.conf changed: LogLevel warn MaxLogSize 1m SystemGroup lpadmin Port 631 Listen /var/run/cups/cups.sock Browsing On BrowseOrder allow,deny BrowseAllow all BrowseLocalProtocols cups dnssd ldap slp DefaultAuthType Basic WebInterface yes <Location /> # Allow remote administration...

--- Begin Message ---Dear Debian User, Further information on your issue was requested some time ago but there has been no response from you. Use of our limited, volunteer supported resources is best served by not keeping open inactive bugs any longer than desirable, especially when the package concerned is older than the current stable Debian version. Consequently, the report is now being closed. You may, of course, wish to review the reported problem. It would be appreciated if any future investigation could be conducted using the testing or unstable distributions. If considered necessary, this report could be re-opened or a new bug report, possibly referencing this one, submitted. Please note there are now separate cups and cups-filters packages. Thank you for your report. Regards, Brian.
