[Bug 525959] Re: 093a:2460 Webcam (Pixart PAC207BCA) - inverted LED logic
Yuri Glushkov, thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/525959/comments/35 the bug has been fixed in the latest development version of Ubuntu - Trusty Tahr. This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.

It would be nice to have a backport at least for the latest LTS version. Anyway, why the status should be Invalid?

Yuri Glushkov, thank you for contacting the upstream mailing list. Regarding this post https://bugs.launchpad.net/ubuntu/+source/linux/+bug/525959/comments/32 : >"[4.] Kernel version (from /proc/version): Linux version 3.2.0-32-generic-pae" Despite how this issue has been identified by downstream to be an upstream issue, please be mindful then when you provide information to upstream kernel.org developers and triagers, you should be booted into the newest upstream mainline kernel available that demonstrates this problem. 3.2.0-32-generic-pae is a Ubuntu kernel, not an upstream mainline kernel. Booting into the mainline avoids some potentially dismissing your problem as a downstream/distro problem only. For more on this, please see https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Boot_Into_Mainline_Kernel .

[Bug 525959] Re: 093a:2460 Webcam (Pixart PAC207BCA) - inverted LED logic
** Description changed: Hi all, Problem: The LED on this webcam is always turned on when connected to USB, unless some application uses it - the behavior that is opposite to what is expected. It was tested on Ubuntu 9.10 32 bit, kernel 2.6.31-19-generic. lsusb shows the webcam information as follows: ID 093a:2460 Pixart Imaging, Inc. Q-TEC WEBCAM 100 Suggested solution: The driver for this camera is gspca_pac207 (located at /lib/modules/2.6.31-19-generic/kernel/drivers/media/video/gspca). In the driver source file pac207.c it can be seen that the bit 1 of the register at 0x41 controls the LED. Looks like it was assumed that '0' at this bit turns the light off, when actually '1' does that. After I've changed the value of this register to the opposite, the re-compiled driver works correctly and the LED is on only when the camera is in use. I've attached the modified pac207.c.
