Re: [Linux-uvc-devel] Genius FaceCam 310
This is a bit strange, do you have more than one video device ? What do you have now as /dev/video0 ? No, this happened after I configured ALSA so the audio capture device integrated in the camera, will be taken as the second soundcard (I already have one that I prefer to be the default soundcard). I'm not saying it is related but after doing this, the camera started to be /dev/video1. Nothing really changed anyway, webcam kept on same way. Is there any way to detect and fix the bandwidth problem ? check this thread: http://www.mail-archive.com/linux-usb-us...@lists.sourceforge.net/msg14838.html Thanks I will look into it. I presume I have to rebuild the kernel in order to get those bandwidth load reports I see in this thread, right ? The other thing is once I detected the problem is the bandwidth, what should I do ? how do I add a second USB controller to my computer ? I wonder if ANYONE here has tried this camera and make it work...

Re: [Linux-uvc-devel] Regarding porting of UVC driver on 2.6.18 kernel

Has anyone ported UVC driver to 2.6.18 kernel(Monta Vista Linux)? Any link or pointer will be very helpful. 2.6.18 is very old. It will probably be possible to backport the driver, but it won't be easy. I can't help you there. -- Regards, Laurent Pinchart ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Have you tried the FIX_BANDWIDTH quirk ? OK... Got to ask... What does the FIX_BANDWIDTH quirk do? (And how?) Also... What controls whether a webcam uses USB 1.1 or USB 2? Is that controlled by the USB hardware? Or could a kernel driver set a USB 2 connected device to run at USB 1.1 speed?

Claudio hi, 2010/11/24 malef...@malefico3d.org: Hi Laurent, http://www.pasteall.org/17101 is the output of lsusb -v, line 176 starts blurb about webcam. Have you tried the FIX_BANDWIDTH quirk ? No, where is that ? kernel source ? just do: rmmod uvcvideo modprobe uvcvideo quirks=128 This will make the driver calculate the needed usb bandwidth for your camera, some devices just request the maximum value and this may cause problems if other devices are connected to the same controller. If I'm not mistaken this will only work for uncompressed streams (yuv). Regards, Paulo Thanks for the feedback !

Re: [Linux-uvc-devel] Genius FaceCam 310
YESSS !!! Thank you Paulo, I tried that and I could get image in guvcview :D I guess I have to add this to /etc/modprobe.d/somewhere_in_slackware but I guess I shouldn't have too much trouble with that. Now I wonder if there is a way to use higher resolutions or is it a limitation of usb or driver or you_name_it ? All I can use right now is 176x144. when trying to go higher (320x240) I get the previous errors saying there is no space left in device. Anyway, thanks again !
