http://bugzilla.novell.com/show_bug.cgi?id=562282 http://bugzilla.novell.com/show_bug.cgi?id=562282#c2 --- Comment #2 from Peter Küppers 2009-12-13 20:27:57 UTC --- Hello Johannes, thank's for your help. The thing with the printer is getting worse. When I try to install the printer with docking-station (printer->parallel->dockingstation->usb->laptop) via YaST or cups webinterface, the laptop freezes suddenly on detecting the printer. I've found bug 229231, but it didn't gave a solution. I tested now to install the printer on laptop directly (printer->parallel->laptop) and it works, but only until I connect the docking-station (without printer). Steps: - booting - switch on printer (it works) - connect docking-station (fails, cause lp- and parport-enumeration changes) see below. I suppose, that there is something wrong with udev-configure-printer. That would explain maybe the info from hwinfo --usb (see above)? Maybe also there is trouble with the uss720 module in this kernel. I get sometimes errors like this: kernel: [ 518.056084] get_1284_register timeout kernel: [ 518.056266] uss720: async_complete: urb error -104 I also tried https://bugzilla.novell.com/show_bug.cgi?id=264219#c1 which worked for me on openSUSE 11.1, but since the printer is no more recognized on /dev/usb/lp0, it don't work.

A complete and sudden machine freeze (i.e a stop of the kernel) is again a low level issue. When it works directly (printer->parallel->laptop) it proves that it works regarding the printing system (i.e. when the low level parpoprt stuff works, the printing system works too - of course). When it does not work with the docking-station in between it is a lower level issue that the communicatin via parport and/or USB does not work normally with the docking-station in between and of course you see then various errors in the printing system layer as a consequence. udev-configure-printer is a only magic full automated printer setup tool and when it fails the only consequence is that you won't have an automated printer setup. In your case I recomend to remove the udev-configure-printer RPM (you could use in yast2-printer the "Autoconfig Settings") to get it out of your way because in your case it doesn't work and in the worst case it might even cause whatever unexpected trouble. Because of all this it is not an issue in the printing system but a lower-level device communication issue because the printing system (CUPS and printer drivers) uses the existing device communication stuff but the printing system does not do any kind of setup of the lower level device communication stuff. Perhaps it might be even a kernel related issue but I have no knowledge at all about docking station issues and therefore I assign it back to "Mobile Devices", hopefully someone there has better knowledge how to debug such issues.

From what I see in your log messages:

Without the docking-station in between you have ------------------------------------------------------------------ kernel: ... parport1: Printer, Hewlett-Packard HP LaserJet 1100 .. kernel: [ 1448.119427] lp0: using parport1 (interrupt-driven). ------------------------------------------------------------------ and the device communication works via /dev/lp0 and the CUPS device URI is accordingly parallel:/dev/lp0 But with the docking-station in between you have ------------------------------------------------------------------ kernel: ... parport3: Printer, Hewlett-Packard HP LaserJet 1100 .. kernel: ... lp1: using parport3 (interrupt-driven). ------------------------------------------------------------------ so that with the docking-station in between the number of the parport where the printer is connected to has changed so that device communication may now works via /dev/lp1 and a matching CUPS device URI of parallel:/dev/lp1 Test if device communication works via /dev/lp1 according to http://en.opensuse.org/SDB:Installing_a_Printer as root with echo -en "\rHello\r\f" >/dev/lp1 To change the CUPS device URI use as root lpadmin -p hplaserjet1100A -v parallel:/dev/lp1 Please report if it works via /dev/lp1. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I found out, that the module uss720 (loaded for the parallel port on the docking station) freezes the system. Removing it and putting it in the blacklist for modprobe let 'yast printer' do the autodetection. As it's said by the module (on loading):

I'm still struggling a little bit with the result of the autodetection, but I'll give my solution here. I also will try /usr/lib/cups/backend and give the result.

From the printing system point of view

From the current point of view the most reasonable bug resolution is WONTFIX which means in this case

Theoretically there might be a bug in the lower level device communication software but from my non-expert point of view it is more likely that this special hardware is just not better supported and won't get better supported unless a software contributor who has this special hardware could implement better support for it (if this is possible at all). Conclusion: that the reported issue is indeed a valid issue and the root cause might even be fixed, but most likely not with reasonable effort.
