Comment 3 for bug 491346

I doubt it's completely fixed. I'm running Lucid (upgraded from Karmic) with hplip 3.10.2-2ubuntu2 and almost all of the files in /etc/udev/rules.d use SYSFS, thus causing the distracting error messages at boot time.

An example from file 86-hpmud-hp_laserjet_1020.rules:

# hp_laserjet_1020
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="03f0", SYSFS{idProduct}=="2b17", PROGRAM="/bin/sh -c 'X=%k; X=$${X#usbdev}; B=$${X%%%%.*}; D=$${X#*.}; logger -p user.info loading hp_laserjet_1020 firmware $$B $$D; printf %%03i:%%03i $$B $$D'", RUN+="/bin/sh -c '/usr/bin/hp-firmware -y3 -s%c &'"
