Bug 118883 – sys-kernel/gentoo-sources-2.6.14-r5 breaks USB printing

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tom Smith 2006-01-13 07:59:15 UTC]

My Lexmark Optra E312 printer works fine with gentoo-sources-2.6.13-r3.  With any of the stable gentoo 2.6.14 kernels, including 2.6.14-r5, I always get an invalid argument error when attempting to print.  For example:

# cat print.ps > /dev/lp0
cat: write error: Invalid argument

A similar error appears in the cups 1.1.23-r7 web interface when trying to print from an application or trying to print a test page from the web interface.  cups 1.1.23-r4 also produced the same error.

I confirmed that lp0 is being created when I plug the printer in, so it appears to be the correct device.  USB printing is enabled in the kernel.  dmesg shows:
Jan 13 10:40:43 [kernel] usb 1-5.4: new full speed USB device using ehci_hcd and address 6
Jan 13 10:40:43 [kernel] drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 6 if 0 alt 0 proto 2 vid 0x043D pid 0x000C

Steps to consistently reproduce:
1. install 2.6.14 series kernel
2. attempt to print
Result: invalid argument error message
Expected result: printing

Steps to temporarily fix:
1. reinstall 2.6.13 series kernel

Adding kernel herd because it is kernel related.
Can you please try with 2.6.15? Maybe there is already a patch for this issue.

[Comment 2 kfm 2006-01-14 14:43:50 UTC]

Yes, please test 2.6.15. Also, please test the following patch against your 2.6.14 tree (and 2.6.15 if that doesn't fix it). You can apply in the following manner:

  # cd /usr/src/linux
  # patch -p1 < /path/to/usblp-ioctl-compat.patch

Then rebuild/reinstall the kernel/modules.

I tried both the patch and gentoo-sources-2.6.15.  Neither fixed the problem.

One other thing that I noticed: /dev/lp0 has device number 180,0 in 2.6.13, but 189,3 in 2.6.14 and 2.6.15.  I'm using the latest stable udev, 070-r1.

[Comment 6 kfm 2006-01-15 22:59:49 UTC]

Attaching another patch which brings the driver in 2.6.14 into parity with 2.6.15-git11 (you'll need to revert the previous patch). Does this help? Also, for the purposes of testing please also make sure your udev rules are consistent with the package defaults. Back up /etc/udev if necessary then:

  # rm -rf /etc/udev
  # emerge --ask --oneshot udev
  # /sbin/udevstart

That same procedure applies when switching udev versions too.

udev-079 was marked stable a few days ago.  upgrading to this seems to have fixed printing with gentoo-sources-2.6.14-r5 without any patches.

[Comment 9 Greg Kroah-Hartman (RETIRED) 2006-01-20 11:37:07 UTC]

good, marking this closed.
