Title:
USB Printer not re-enabled after printer power off
Status in “system-config-printer” package in Ubuntu:
Confirmed
Bug description:
Possibly udev bug.
After last updates to Lucid (10.04 LTS).
libusb-0.1-4 2:0.1.12-14ubuntu0.2
libusb-1.0-0 2:1.0.6-1
udev 151-12.2
uname -a gives
Linux fitsserver 2.6.32-26-server #48-Ubuntu SMP Wed Nov 24 10:28:32 UTC 2010
x86_64 GNU/Linux
I have a server running 24/7 which has a canon USB printer connected. The
canon is on a switched mains supply so is turned off every day when not in use.
Previously this worked fine - the server would see the canon turned on and
the Print queue would be re-enabled.
After the last round of updates this no longer works. Replugging the printer
will make it work.
I have just tested and the syslog is below with interline comments at ***:
Thanks
David
