[Bug 420797] Re: CUPS 1.4.0, USB backend hangs
I'm going to try printing from a friend's HP printer. If that works then maybe it is time for me to replace the ageing Lexmark with a new HP. If I try to print and no paper is in the paper feeder, the power light will flash. Upon inserting paper and pressing the "continue" button, the printer will wait for a while then sometimes just eject the paper. Other times 1 page will print and then no more. ** Attachment added: "errorlog.txt" http://launchpadlibrarian.net/31289735/errorlog.txt -- CUPS 1.4.0, USB backend hangs https://bugs.launchpad.net/bugs/420797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 420797] Re: CUPS 1.4.0, USB backend hangs
I don't know if this helps, but here is the output of strace
poll([{fd=0, events=POLLIN}, {fd=4, events=POLLIN}], 2, -1) = 1 ([{fd=0,
revents=POLLHUP}])
(... repeated in infinite loop)
and here is output of lsof :
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
usb 9846 lp 4u unix 0x88007e521b80 0t0 42632 socket
so the "hanging" usb process keeps polling a UNIX domain socket in vain.
My best guess is that cups forgets to close the UNIX domain socket that
it uses to communicate with its backend after printing. This makes
subsequent printing unavailable.
I'm using cups version 3.6.8-9ubuntu3 in karmic koala.
A workaround to the problem is to create a cron task that kills every
minute any process which name starts with "usb://". Yes, that's ugly,
dangerous, and miserable, but it helps me not being killed by my
girlfriend who needs to print from her macintosh.
