Generally works with the min12xxw driver.
following the steps leads to my printer being seen, but it will only
fire off 1 test page:
Must be the usb hanging issue after the first one is solved?
Oddly, even after a hard boot, the printer still will not print one more
Same here. My printer was working fine before I upgraded to karmic, then
stopped working after the distribution update.
First, the printer was not seen by CUPS. Solved it by:
- blacklisting usblp kernel module
- changing group of /dev/bus/usb/00x/00y device
- not letting apparmor supervise
Eric,
I have noticed after those owner/rights manipulations and detecting a
printer last one stays in suspended state. Try to resume it in CUPS web
admin frontend.

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 :

I agree the usb hanging bug is a different bug from the printer not
seen by cups problem described by this issue.
I would say the bug described here is basically solved by the three-step
method explained above.
Therefore I suggest we continue the discussion at
ilna : killing the print job and resuming the printer does not help.
Only killing the process named usb://EPSON something helps. The print
job disappears from the print queue cleanly then.
It really looks like CUPS does not close some socket it is writing on
after printing, so the usb process
Hello all,
Same problem with EpsonRX425, I had to do it through lpadmin:
lpadmin -p RX425 -P /etc/cups/ppd/Stylus_Photo_RX420.ppd -v /dev/usb/lp0
assuming that I put the pdd file from a backup and followed the advice of the
command
FileDevice dans « /etc/cups/cupsd.conf ».
I add FileDevice=yes

usblp Kernel module needs to be removed and /dev/bus/usb/*/* made
In addition to removing the kernel module, the CUPS usb backend needs
full access to the /dev/bus/usb/*/* files to get fully functional. The
settings in /etc/apparmor.d/usr.sbin.cupsd need to get adapted.
Currently, I get audit messages like that in /var/log/syslog:

@Till - Thanks! Not that it works yet, but at least someone who knows
what's going on has taken interest :)
Confirmed, after rmmod, I get a new message after the old ones:

Oh wait, no, that message was there before... I don't see a difference,
then.

run the command line

Thanks, I must be doing something wrong... now I get all the messages

Have removed usblp module, also removed cupsd from apparmor, restarted
cups - still a printer isn't visible by cups.
Which additional info must I supply?

Thanks again for taking time with this...
Some commands gave errors as a normal user, so I've included both with
