From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: HP1300 on usb worked fine for a long time. Then RPM updates to FC3 cause it to stop working a lot. Sometimes the /dev/usb/lp0 link disappears altogether and it can't find any hardware. I think one time I saw it looking for /dev/hal/usb0 or some such nonsense. Today it won't work again and when I run the FC3 printer config it tells me to write to you. $ system-config-printer No match for USB device: mfr "Hewlett-Packard" model "hp LaserJet 1300" desc "Hewlett-Packard LaserJet 1300" cmdset "PJL,MLC,BIDI-ECP,PCL,POSTSCRIPT,PCLXL" Please report this message in Bugzilla: https://bugzilla.redhat.com/bugzilla Choose 'foomatic' as the component. The only complicating factor that I know of is that I recently obtained the actual ppd file for the hp1300 (instead of the generic one) and put that into /usr/share/cups/model. Version-Release number of selected component (if applicable): foomatic-3.0.2-3 How reproducible: Sometimes Steps to Reproduce: 1. Configure printers with system-config-printer 2. Sometimes things will print, sometimes not! 3. Running system-config-printer again and editing the printer sometimes shows the empty box where the usb devices used to be listed. Actual Results: Printer frustration. Additional info:
The "no match for USB device" message is harmless and can be ignored. It just means that the model is not automatically selected from the list (and this is now corrected in the development package). What kernel are you running?
My kernel is the newest one from FC upgrades, 2.6.10-1.741. Your comment means there is some other reason that the usb device keeps disappearing from the printer's configuration?
Yes, I think this must be a kernel issue of some sort.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
I have found that a total system re-start fixes this problem after the newest FC4 kernel upgrades.
