[linux-uvc-devel] Microsoft Lifecam HD-3000 does not work

[Claudio B. <cla...@gm...>]

I am trying to use my USB Microsoft LifeCam Cinema webcam with Ubuntu
12.04. When not in use, it blinks incessantly and seems to slow down
my system. Using google voice or guvcview (or any other video
application), the camera works for 2 seconds and then freezes. If you
change resolution (or compression method) my camera restarts working
for 2 second and it stops again. Disconnecting the camera makes system
up and running again without slowing down.
I've tried with latest stabile kernel (3.2.7) with same results.

In dmesg.log camera was connected at my system at time 3702.044068.

Some hints always welcome.

Claudio

Hi Claudio,

it can be usbsuspend issue, please take a look here:
http://www.ideasonboard.org/uvc/faq/#faq5

or it can be usb-sound issue (not uvcvideo), in this case you should try:
sudo rmmod snd_usb_audio && sudo modprobe snd_usb_audio ignore_ctl_error=1

[Claudio B. <cla...@gm...>]

Thank you for your answer. I've tried your hints (echo -1 >
/sys/module/usbcore/parameters/autosuspend
 and/or modprobe snd_usb_audio ignore_ctl_error=1) but without
success. Sometimes, and only first time after reboot, webcam works for
two minutes, then i stops and it does not restart even if plugged and
unplugged.

With dmesg I've noticed that when camera works there are not messages,
but when it stops working there are a lot of message like this
[  xxx.xxxxxx] 6:3:1: cannot get freq at ep 0x82. In dmsg.log included
there is my latest attempt:

I've removed snd_usb_audio and uvcvideo module and then
- at 4202 I've executed modprobe snd_usb_audio ignore_ctl_error=1
- at 4233 I've executed modprobe uvcvideo quirks=262 trace=15
- at 4240 I've connected my webcam and launched guvcview
- camera works for two seconds and then it stops (dmesg shows "cannot
get freq at ecc. ecc.")

The led on webcam is on when it works ok, start to blink when camera
stops working.

Any other hints?

Ciao,
Claudio

Hi,

the problem is that video and audio driver fail to work with this cam.
This message is not from uvcvideo, it comes from snd-usb-audio: "cannot
get freq at ep 0x82". What if you black list the snd-usb-audio, will
then video work? If not, can you please do a regression test and find
working kernel? Currently only you can find reason of this bug. You need
need to compile kernel from source.

And one more thing, 3.2.7 is not latest stable kernel. You need to test
at least 3.5.0.

Great: the problem was actually the sound module and the uvcvideo. I had
not thought of putting in the blacklist the snd-usb-audio module. I've
added "blacklist snd-usb-audio" line into /etc/modprobe.d/blacklist.conf
and I've obtained a working webcam. Thank you very much.

The "latest" kernel was not 3.2.7 but 3.4.7, I'm sorry. I've noticed that
bug appears if chrome is loaded but not firefox: maybe googletalk_plugin
trying to force a sample rate not supported by the microphone of the webcam?

I will try to contact the snd-usb-audio develop group. Thanks again for
your help,
Claudio

Re: [linux-uvc-devel] Microsoft Lifecam HD-3000 does not work

[Claudio B. <cla...@gm...>]

SOLVED

I realized I was doing the tests always with Chrome running. I found
that all my troubles were caused by the latest built-in flash player
(pepper version 11.3.31.232). In chrome:plugins, advanced settings,
I've disabled pepper flash player, leaving only adobe flash player
11.2.r202. All of troubles are gone, snd-usb-audio was innocent...

Thank you again,
Claudio
