CPIA webcam support has sysfs problem

Have this fixed in my git tree for gutsy.

This bug has had no activity for a while. This is a check to see if there is still interest in investigating this bug report.
Has this been fixed in Gutsy and/or later?
Can "linux-source-2.6.15" be marked "Won't Fix" or otherwise?

I just tried my QX3 microscope with both Gutsy and the latest Hardy beta and both worked with gqcam.

I plugged in the USB device, made sure the cpia module is loaded, installed gqcam and then ran "gqcam -v /dev/video0". I also echo'ed "toplight: on" to /proc/cpia/video0 and that turned on the toplight but gqcam has to be running for that to work.

From the kernel output there is no sysfs support yet.
Here is the kernel messages in Gutsy when the device was plugged in and looking at Hardy, it's the same:

[ 7973.144000] Linux video capture interface: v2.00
[ 7973.156000] V4L-Driver for Vision CPiA based cameras v1.2.3
[ 7973.156000] Since in-kernel colorspace conversion is not allowed, it is disabled by default now. Users should fix the applications in case they don't work without conversion reenabled by setting the 'colorspace_conv' module parameter to 1

problem still exists on latest hardy...

same Problem here with Terratec Terracam USB

Beginning with the Hardy Heron 8.04 development cycle the kernel source package naming convention changed from "linux-source-2.6.xx" to just "linux". Going forward, kernel bugs should now be reported against the "linux" package. I'm removing the linux-source-2.6.24 task since this is already reported against the "linux" package.

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.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Hi All,

This bug has been open for quite a while. Can anyone confirm this issue remains with the latest Jaunty Jackalope 9.04 release - http://www.ubuntu.com/getubuntu/download ?

Additionally against the linux-source-2.6.22 task this is being closed as the 2.6.22 gutsy kernel has reached it's end of life - http://www.ubuntu.com/news/ubuntu-7.10-eol. I'm also closing the upstream Linux task as there does not appear to be an upstream bug to link this report to.

Lastly, this is not likely to qualify for a Stable Release Update to dapper so I'm closing the linux-source-2.6.15 task as well.

Again, this will remain open against the actively developed kernel for now if we can get testing and feedback. Thanks.

This bug report was marked as Incomplete and has not had any updated comments for quite some time. As a result this bug is being closed. Please reopen if this is still an issue in the current Ubuntu release http://www.ubuntu.com/getubuntu/download . Also, please be sure to provide any requested information that may have been missing. To reopen the bug, click on the current status under the Status column and change the status back to "New". Thanks.
