Description Patrick 2010-10-17 10:11:05 EDT
Description of problem:
Logitech Orbicam (046d:0896) only works with Cheese when cheese is started multiple consecutive times. To my totally untrained eye it seems that the wrong video device is created/released.

Version-Release number of selected component (if applicable):
2.6.35.6-43.fc14.x86_64

How reproducible:
Start cheese, quit cheese, start cheese again, quit again etc. Continue this until the cam led lights up and the cam starts working.

Steps to Reproduce:
1. modprobe -v gspca_vc032x
2. start cheese - green led on cam does not light up and no images from cam
3. stop cheese and start cheese again (cam led may light up & cam may work) or stop cheese again and start cheese again (cam led may light up & cam works)
  
Actual results:
Cam does not work when cheese is started for the first time

Expected results:
Cam led lights up & the cam works

Additional info:

Steps I did to reproduce this with output. Please note the messages were gspca creates video0 but releases video1 or creates video1 and releases video0 when cheese is terminated (and the cam did not work).

Manually insert gspca_vc032x

Comment 1 Fedora End Of Life 2012-08-16 14:41:57 EDT
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping
