[Linux-uvc-devel] Quickcam Pro 9000 LED control
Hello list, I have a Quickcam Pro 9000 and I can't control the LED: # uvcdynctrl -d video0 -s 'LED1 Mode' 0 ERROR: Unknown control specified. Effectively, running uvcdynctrl -c doesn't show this control, but I thought all new models supported the LED control. Is this a hardware limitation or a software limitation? My camera's usb id is: 046d:0809 Thanks. Alan ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
Re: [Linux-uvc-devel] Quickcam Pro 9000 LED control
Thanks a lot, I ran udevadm and now the led control is working :) By the way, I just had a thought that it would be cool to export the led control of the webcam using leds-class: http://www.mjmwired.net/kernel/Documentation/leds-class.txt Alan On Fri, Apr 30, 2010 at 12:41 AM, Paulo Assis pj.as...@gmail.com wrote: Hi, you need to import the extension controls first. If you have libwebcam installed try retriggering udev with udevadm trigger or by replugging your camera. For Ubuntu (at least), udev doesn't seem to work very well when cold plugging the webcam. You can also use guvcview (run it as root at least once).

[Linux-uvc-devel] Framerate of Quickcam Pro 9000
I have a problem with my camera: the framerate is too low. I tested the camera using mplayer and motion with different light levels. So I tried to fix it by following the instructions here: http://www.quickcamteam.net/documentation/how-to/how-to-maximize-the-frame-rate Unfortunately its still slow, and I think I messed up something because every time I run uvcdynctrl I get this error: [libwebcam] Unknown V4L2 private control ID encountered: 0x0A046D04 (V4L2_CID_PRIVATE_BASE + 33844484) So I think at some moment I used an invalid parameter, so I thought I could rmmod and modprobe uvcvideo to fix it, but no. Reconnecting the camera doesn't help either. So is this an invalid parameter? If so, where is it stored, in some memory inside the camera? And how do I fix the framerate issue? Thanks!

Could you please test the latest SVN revision and tell me if it helps ? Alan Stern said the problem was that USB needed to move to the new PM ops. He posted a patch for this which fixed my problem (the scary WARNING with call-trace). So I'll try to test SVN but it's not very interesting :-). The warning message in the kernel log came from the USB subsystem core, but the driver was also kinda faulty as it didn't implement all power management callbacks (even though the missing one isn't mandatory). The two patches address different issues, they are complementary. Ok, thanks for both of your explanations. I tested SVN uvcvideo on a kernel without Alans patch, and it's fine. I can suspend and resume without any errors. I also checked it works using the Kopete settings dialogue, which includes a webcam demo.

It doesn't have reset_resume, so it is marked for rebinding. That in turn
triggers the warning because the parent is still asleep. That shouldn't
happen if we walk the device tree properly. Can you add a printk
to device_pm_add() to print out the parent? We need to rule out that the
device tree is bad.

Done. (For the record, I've posted the results at

[Linux-uvc-devel] 2.6.27-rc2: uvcvideo breaks after suspend to ram
I don't use the webcam on my EeePC; I just happened to try it while testing 2.6.27-rc2. I don't know about any other version so this isn't neccessarily a regression. I think I tested it using Kopete, then later I got this warning on resume. I definitely didn't have Kopete open when I suspended though.

I'm using a stock Ubuntu 2.6.22 kernel so I wont have the latest
uvcvideo but since I don't see this device id on your supported list
I'm guessing that wont work either.
Let me know if you need to me to do anything or need more information.

Re: [Linux-uvc-devel] New Camera Feiya Technology 090c:b370
The camera might have crashed when getting the first request. Please try the attached patch and let me know if it helps. The Failed to query (135) message should disappear complete. If it doesn't, you're still using the unpatched driver. Thanks for your help. The driver now loads without any problems, and a video device gets registered. Unfortunately the errors were only delayed until I tried to use it. This is kopete scanning the device: uvcvideo: Failed to query (135) UVC control 2 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 3 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 7 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 6 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 9 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (1) UVC control 1 (unit 0) : -110 (exp. 26). uvcvideo: Failed to query (135) UVC control 2 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 3 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 7 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 9 (unit 3) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 6 (unit 3) : -110 (exp. 2).

Re: [Linux-uvc-devel] New Camera Feiya Technology 090c:b370
It turns out that the GET_DEF wasn't causing the original error at all. The old Ubuntu version of uvcvideo must be doing something different. So I'm now running the unpatched code I grabbed from svn earlier today and I've got it kinda working. luvcview -f yuv works, and once I figured out that there was a channel 0, I got ekiga working too. The one program I wanted to use though, kopete, still sends errors to syslog and somehow crashes the camera too. I'll play more tomorrow.
