I don't see how this would have any difference with 197-r8 or 198-r1, but is CONFIG_USB_PRINTER=n set in kernel? The "new" cups doesn't like CONFIG_USB_PRINTER=y and uses libusb instead.


I have CONFIG_USB_PRINTER set in my kernel:

Code:

# grep -i config_usb_printer /usr/src/linux/.config
CONFIG_USB_PRINTER=y


However, that should be fine with CUPS (even with 1.6.1) as long as USB support (libusb) is not included at the time of compilation:

Code:

# emerge -av cups

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] net-print/cups-1.6.1  USE="X acl dbus filters pam ssl threads -avahi -debug -gnutls -java -kerberos -python (-selinux) -static-libs -systemd -usb -xinetd -zeroconf" LINGUAS="-ca -es -ja" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB


If I recall correctly, it simply has to be one or the other--kernel USB printing support (via usblp) OR built-in USB support in CUPS (via libusb).

Also, I didn't change anything about my kernel when the errors were occurring. Instead, I just downgraded UDEV.

Cheers,
Nathan Zachary

I think I've narrowed this down.

Please look at the Gentoo bug and try the patch from there. You can just apply the patch directly in /lib/udev/rules.d/ and no re-emerging is necessary since this is just a text file and we are just moving one section from end to beginning.

Upstream commit that broke this in 198:

http://cgit.freedesktop.org/systemd/systemd/commit/rules/50-udev-default.rules?id=22582bb2cbe85b40de5f561589e0468dac769515

Possible patch to the problem:

http://bugs.gentoo.org/462346 (See Comment #3) -> http://bugs.gentoo.org/show_bug.cgi?id=462346#c3

Let me know how it works, preferably in the bug. I'm not sure if "udevadm trigger" is enough after the patch, or if rebooting is required, let me know about that too. Thanks!

@ssuominen,
I have a separate Gentoo install on my box for experiments.
It's more or less identical to the regular one.
I tried downgrading to cups-1.5.2-r4 with udev 198 installed.
All kinds of weird things when I tried to configure cups in my browser.
Never got it going.
Usb printer is not enabled in my kernel,cups has the usb flag set.

I'll wait until the new 198 appears in portage before installing it.
Thanks for all the work you do.
Gerard.

I think I'll wait for one or more people to confirm http://bugs.gentoo.org/show_bug.cgi?id=462346#c3 is OK with 198 and CUPS 1.6.x before making a new revision 198-r2 for ~arch (testing)

Is this patch only applicable for those running systemd? I ask because the patch name includes systemd. If not, I will attempt to patch it and check for results.

Cheers,

Didn't read this bit until now, but just restarted udev and cupsd after patching
I will update the bug as well

The patch is for sys-fs/udev's file 50-udev-default.rules, and is not really dependant on the init system being used, so the patch is for systemd, openrc, and whatever

The fix is in Portage as =sys-fs/udev-198-r2 (and also in 9999 if you re-emerge it)

Upgraded from 197 to 198-r2.
Printing with cups-1.6.1 now works fine.
Thanks ssuominen!
Gerard.

I did as well, and all aspects of printing have returned to normal. For me, it functioned correctly after the "udevadm trigger," but I wanted to migrate to the new naming conventions for network interfaces, so I rebooted as well.

Thank you for the help, Samuli!

Cheers,
Nathan Zachary

@NathanZachary

Before udev was ... makedev() ;)

If I remember well, usblp(?) kernel module creates /dev/usblpx to access an usb printer but cups usb/hp backends (usb/hpio) need /dev/bus/usb/00x/00x instead. Also many printers are bidirectional and they need r access to the device as well.

As user, run 'strace /usr/libexec/cups/backend/usb' or strace /usr/libexec/cups/backend/hp' to see where you get a permission denied. That could help you to identify the origin of the problem.

PS: if lp group needs to be changed to usb as suggested in the bug report, probably the same problem could arise with a scanner connected to an usb all-in-one printer.

@Jimmy Jazz,
My Epson RX560 is a combo with scanner.
Both printer & scanner work fine.
Usblp is ancient history.

I use the the usblp kernel driver with CUPS-1.6.1 without any problems. It may be an "older" driver, but it works just fine. I don't see any reason to use the one bundled with CUPS. If you know of a reason, I would definitely entertain the idea of switching. :)

Unfortunately, I just had to mask >sys-fs/udev-197-r8 in order to keep my printer working. I emerged the latest ~ release of udev today, and my printer stopped working again. Would it be best to open a new bug report for it?

Cheers,
Nathan Zachary

If you don't the ~version that doesn't work will be stabilize with your bug in it.
Better report before this happen to save yourself and all stable users with a printer no ?

What do you mean?

gerard82 posted Wed Mar 20 that "Upgraded from 197 to 198-r2. Printing with cups-1.6.1 now works fine."

to which you replied Wed Mar 20 like: "I did as well, and all aspects of printing have returned to normal. For me, it functioned correctly after the "udevadm trigger," but I wanted to migrate to the new naming conventions for network interfaces, so I rebooted as well. "

This was related to broken .rules in udev itself and the fix has since been imported to upstream git and is part of udev-200, 202, 9999

But now you are saying you had to mask >sys-fs/udev-197-r8 to get printing working again?

Sorry, but that doesn't make any sense to me.
