udev-174-1 breaks printer detection [solved by upgrading udev]

Hey,

the last update to udev-174-1 breaks the detection of my printer, a Canon PIXMA IP4000. CUPS isn't able to detect it any longer. I had to downgrade the package. Did I miss anything during the update?

Didn't help, I even tried to reboot. I also added the module usblp (normally blacklisted), but no chance.

This udev version also breaks my custom udev rules. My DSLR is detected as my other digital camera. :-/

Is this still a problem? Please make sure that you don't have any deprecated keys in any of your rule files (SYSFS, BUS and ID), these are no longer supported, and unpredictable (seemingly unrelated) things will happen if you have them.

There was a change to the printer rules, so if the above does not help, please open a bug report.

@Silenzium: if you post your rules maybe we could figure out what is going on :-) Also add "udevadm info -a -n /dev/<your camera>" of both your cameras.

I guess i had the same issue with my Brother HL-2030 printer connect via USB.

I got it working again by creating a udev rule (i.e. /etc/udev/rules.d/10-cups-usb.rules) with the following content:

ATTR{idVendor}=="04f9", ATTR{idProduct}=="0027", MODE:="0664", GROUP:="lp"

The idVendor and idProduct you get from the associated values from lsusb.
Mine looks like

Bus 002 Device 010: ID 04f9:0027 Brother Industries, Ltd HL-2030 Laser Printer

btw: there is a new udev package (udev-175-1).

The update to udev-175-1 seems to solve my problems.

btw: I don't have my printer in my udev rules and the other rules look like this:

# DSLR (Nikon D80)
KERNEL=="sd?1", SUBSYSTEMS=="scsi", ATTRS{model}=="D80", SYMLINK+="nikon_d80"

# Digitalcamera (Fujifilm Finefix A303)
SUBSYSTEMS=="scsi", SYSFS{vendor}=="FUJIFILM", NAME="fujifilm"
