Package: cupsys Version: 1.1.23-10sarge1 Severity: normal I was trying to write a script for udev that could automatically enable my printer if I turn it on. However, cups uses device URIs like "usb://Samsung/ML-1610" in printers.conf, which are impossible to map onto USB ids, device names or other sysfs properties. Therefore it is impossible to find out from outside of cups which printer was connected or turned on.
Internally, cups determines which usb device an USB DeviceURI belongs to by polling all present usb printers (i.e., all devices in /dev/usb/lp*) and ioctl()ling them for their ieee1281 manifacturer and model strings. It would be nice if cups could export this functionality (currently in backend/ieee1284.c) to a userspace utility so that it would be possible to check from the command line what DeviceID is associated with a specific usb printer device. It would be even nicer if this utility would be able to return the specific cups printer (if any) a specific usb device is associated with (by parsing printers.conf and matching the DeviceURI). Something like: > cups_usbinfo /dev/usb/lp0 DeviceURI usb://Samsung/ML-1610 Printer MySamsungPrinter -- System Information: Debian Release: 3.1 Architecture: i386 (i686) Kernel: Linux 2.6.8-3-686 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages cupsys depends on: ii adduser 3.63 Add and remove users and groups ii debconf 1.4.30.13 Debian configuration management sy ii libc6 2.3.2.ds1-22sarge4 GNU C Library: Shared libraries an ii libcupsimage2 1.1.23-10sarge1 Common UNIX Printing System(tm) - ii libcupsys2-gnutls10 1.1.23-10sarge1 Common UNIX Printing System(tm) - ii libgnutls11 1.0.16-13.2sarge2 GNU TLS library - runtime library ii libpam0g 0.76-22 Pluggable Authentication Modules l ii libpaper1 1.1.14-3 Library for handling paper charact ii libslp1 1.0.11a-2 OpenSLP libraries ii patch 2.5.9-2 Apply a diff file to an original ii perl-modules 5.8.4-8sarge5 Core Perl modules ii xpdf-utils 3.00-13.6 Portable Document Format (PDF) sui ii zlib1g 1:1.2.2-4.sarge.2 compression library - runtime -- debconf information excluded -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
