No uevents for parport devices when parport modules loaded

[RGilbert]

Usability issue.

XSANE cannot find scanner on parallel port for default user.
XSANE recognizes parallel port scanner when called using sudo.

scanner should be detected and xscan should execute for default user without the need to change user permissions.

the parport devices are not created when the parport modules are loaded

[Scott James Remnant (Canonical) (canonical-scott)]

udevmonitor prints the received event from the kernel [UEVENT]
and the event which udev sends out after rule processing [UDEV]

set a milestone; would be nice to have parallel ports supported out of the box

[ImmanuelOffice (office-immanuelministries)]

Is there a workaround for this? I can't access my scanner as a normal user. Is there something I can set in udev to make it work?

[ImmanuelOffice (office-immanuelministries)]

I was able to get this to work by adding my normal user to the lp group in /etc/groups, and then logging out and logging in again

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
