[Bug 162016] Re: cups printjobs unload /dev/usblp0
Hi there. Time goes by ... I forgot to notify that my bug vanished after upgrading to Maverick. So I don't have this problem anymore now. Thanks so far.

The removal of usblp0 is not a bug, as already discussed here. Please do not reopen this bug. If you have problems with printing, this is due to another problem. Report a new bug for that.

[Bug 162016] Re: cups printjobs unload /dev/usblp0
Many thanks to You all. Today I observed a peculiar message. Please, don't blame me if this is a no-sense question, or if it is a FAQ ... The printer (HP1320N) prints almost well (I'm still working around some HPLIP problem - the libusb problem has been fixed - see bug #427805). However, everyday I get such a message in /var/log/kern.log kern.log.1:Jul 12 08:33:35 uffcom2 kernel: [ 2418.550539] usblp0: removed kern.log.1:Jul 12 08:56:30 uffcom2 kernel: [ 3793.783509] usblp0: removed kern.log.1:Jul 13 10:28:54 uffcom2 kernel: [ 7687.284389] usblp0: removed kern.log.1:Jul 14 08:45:24 uffcom2 kernel: [87878.985389] usblp0: removed kern.log.1:Jul 14 09:31:29 uffcom2 kernel: [90643.473467] usblp0: removed kern.log.1:Jul 15 14:00:32 uffcom2 kernel: [ 2129.233394] usblp0: removed kern.log.1:Jul 16 09:18:02 uffcom2 kernel: [ 5805.839505] usblp0: removed kern.log.1:Jul 16 09:19:08 uffcom2 kernel: [ 5871.363425] usblp0: removed kern.log:Jul 20 09:17:22 uffcom2 kernel: [ 5367.939394] usblp0: removed kern.log:Jul 21 09:31:54 uffcom2 kernel: [ 2843.359392] usblp0: removed kern.log:Jul 22 09:53:59 uffcom2 kernel: [ 8377.334403] usblp0: removed For instance, consider the last log entry at 09:53:59. The system booted up at 07:35 today, then I printed some documents before 09:53 and also some documents later, both from LP command line interface, PDF from document viewer and email from Thunderbird. The toolbox jobs viewer showed all the tasks done. What does it mean usblp0: removed ? Removed from where? Thanks.

[Bug 162016] Re: cups printjobs unload /dev/usblp0
I'm using Ubuntu Hardy Heron (everything up to date, original install was beta5 I believe), default detection of the printer (detected automatically to hp:/usb/HP_LaserJet_1020?serial=JL2R4KC), and I confirm this as NOT being the wrong URL. I have the exact same problem, HP LJ1200, prints ok from OpenOffice, but not from Evince. Running hp-makeuri on the proper usb combo (on my sys, 006:003) yields the same URL: hp:/usb/HP_LaserJet_1020?serial=JL2R4KC. Even if the reason is not the specified one, the symptoms are valid and the bug shouldn't be closed. Is there any log I can provide? ** Changed in: hplip (Ubuntu) Status: Invalid = Confirmed -- cups printjobs unload /dev/usblp0 https://bugs.launchpad.net/bugs/162016 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 162016] Re: cups printjobs unload /dev/usblp0
The removal of the /dev/usblp0 device is not the reason why some jobs do not get printed. The device is not needed when printing via HPLIP. The problem that some files do not get printed is probably another bug.

If you are using CUPS this means in general you should always use the HPLIP's hp backend (ie: hp:/usb/...) instead of the standard CUPS usb backend (ie: usb://...). I use HP1018 with Cups and HPLIP's hp backend (ie: hp:/usb/...) but I have the same problem. The only way I have to resurrect my printer is booting Windows an rebooting to Ubuntu. -- cups printjobs unload /dev/usblp0 https://bugs.launchpad.net/bugs/162016 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 162016] Re: cups printjobs unload /dev/usblp0
The disconnection of HP printers from the usblp kernel module is done by HPLIP's hp backend, the backend used by all automatically generated queues for HPLIP-supported HP printers. It happens also when other HPLIP tools, like hp-toolbox, access the printer. Printing via the print queue is not affected by this, but the disconnection leads to other problems, especially HAL does not see any more when the device is connected or disconnected, so it cannot disable the print queue while the device is disconnected, it also breaks automatic print queue setup for the HP LaserJet 1018 and 1020 due to the automatic firmware upload being done by an HP tool and so the device already disappears for HAL before an automatic print queue setup can be done. To the developers from HP: Is it perhaps possible to still give the full functionality of the printer via HPLIP but without decoupling the printer from the usblp kernel module? ** Changed in: hplip (Ubuntu) Importance: Undecided = Medium Assignee: (unassigned) = David Suffield (david-suffield) Status: New = Confirmed -- cups printjobs unload /dev/usblp0 https://bugs.launchpad.net/bugs/162016 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 162016] Re: cups printjobs unload /dev/usblp0
Sorry, HPLIP uses libusb/usbfs instead of usblp. Libusb uses the /dev/bus/usb/xxx/xxx device node instead of the /dev/usblp0 device node. Since usblp and libusb cannot claim the the same usb device, any HPLIP device I/O usage (ie: scanning, printing or faxing) will remove usblp from the /dev/usblp0 device node. If you are using CUPS this means in general you should always use the HPLIP's hp backend (ie: hp:/usb/...) instead of the standard CUPS usb backend (ie: usb://...). The hp backend will always use the libusb device node. If you try to use the usb backend the /dev/usblp0 device node may not be available. Currently hal_lpadmin calls hp-info and hp-probe which are io intensive and will interfere with hp-firmware download for the LJ1018 and LJ1020. Because of this interference HAL will not see these printers at plug-in- play time and disable the print queue. The hp-info and hp-probe calls in hal_lpadmin should be replaced with the hp-makeuri call. The udev sysfile information will provide the usb bus and device information necessary for the hp-makeuri bbb:ddd command. Hp-makeuri will return a valid HPLIP uri if the usb device is supported by HPLIP. Hp-makeuri is a light weight call that has very little io overhead. The hp-makeuri command will not interfere with the hp-firmware download. -dave -- cups printjobs unload /dev/usblp0 https://bugs.launchpad.net/bugs/162016 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
