Microsoft Life Cam Still Not Recognized?

[ckozler]

Hi,

Firstly, let me say that this is a very useful product and should
receive a lot more publicity than it is getting. So, right onto
business. I have read this thread from the Ubuntu Forums:

http://georgia.ubuntuforums.com/showthread.php?p=5918300

As you can see, I have posted on the last page that it seems the
camera is still not being recognized. Whomever "IntuitiveNipple" is
had stated that he rebuilt the DKMS for hardy and that the package was
available. So I installed the package that he provided the apt link
for. At first nothing happened so I restarted my computer then
proceeded to do "demsg | grep micro" and what had appeared was:

[15:13:42][eax@kozler-linux:~]$ dmesg | grep "micro"
[ 46.843020] microdia: Microdia USB 2.0 webcam driver loaded
[ 46.843069] microdia: Camera 045E:00F4 not supported.
[ 46.843084] usbcore: registered new interface driver
usb_microdia_driver
[ 46.843088] microdia: v2008.09 : Microdia USB 2.0 Webcam Driver
[15:13:43][eax@kozler-linux:~]$

Which is weird that it is saying it is not supported when it is stated
on this groups page and in that post that Device ID 045E:00F4
(Microsoft Life Cam VX-6000). Also, I have read some pages around
here about this and one that I saw was:

http://groups.google.com/group/microdia/browse_thread/thread/a09aee095c7bf7e4/1da42e25d478ef82

Which helped to a degree until I got to the post about editing
microdia.h. I have some pretty decent programming experience (nothing
comparable to you guys) so I was confident in making the change to the
header file. Well, I opened the macrodia header file and all the
relative microsoft things seemed to be in place already. I saw
something about running the "init" sequences, does that have to deal
with insmod? Either way, /dev/video0 isnt being created and
(obviously) the webcam is still not working. I hope to get some more
information from you guys. Also, here is the information you guys
need as well.

I could not get the bridge or image sensor. Im not too keen on
opening up my camera but maybe if its a last resort I will. Hopefully
what I have provided is sufficient.

Thank you for your time,
Chuck Kozler

[GWater]

Please download the current source from the git repo and apply this
patch ($ git am *.patch).

Compile it insmod it and tell us whether it works or what does not work.

I had the same problem, but after I applied the patch the driver
works :)

dmesg now says (instead of not recognizing it):
[11924.590791] microdia: Microdia USB 2.0 webcam driver loaded
[11924.591007] microdia: Microdia USB 2.0 Webcam - 045E:00F4 plugged-

[11924.592982] microdia: Microdia USB 2.0 Webcam is now controlling

usb_microdia_driver
[11924.593363] microdia: v2008.10 : Microdia USB 2.0 Webcam Driver

and am able to get images using:
$ mplayer tv:// -tv driver=v4l2:width=640:height=480:fps=25:device=/
dev/video0 -vo x11

great work, i will test it a bit more :)

Could you please test whether your in-built mic works as well?
For example in Skype, you can select "USB..." as audio input and
then try making calls to user "echo123" or better "videoecho123".

Thanks,
Golam

[PaulluaP]

Sound does not work with skype.... I tried the videoecho and it does
repeat my webcam but without sound...

I used settings:

Sound in [USB20 Camera (hw:default,0) ]
or plughw:default

BTW, did you apply the patch "Restores-USB-audio...." from this week's
patches? If not, please apply it from this message

http://groups.google.com/group/microdia/msg/c45c64e257269a36?

Also, please run Skype from a console and report the
error message that you get there (if audio still doesn't work).

Cheers
Golam

[PaulluaP]

I applied the patch usb audio patch (do i also need to apply the other
patches?)

but it still doesnt work... i get this error on the console:

RtApiAlsa: callback thread error (RtApiAlsa: audio read error for
device (USB20 Camera (hw:default,0)): Input/output error.) ...
closing stream.

maybe this is error also relevant:

ALSA lib pcm_params.c:2135:(snd_pcm_hw_refine_slave) Slave PCM not
usable

greets.

I don't think so but you could try with SN9C20X_SCALE patch.
It could affect your video though. Also, please do "make clean"
before running "make" and always un-plug your webcam
before loading new module.

Above is the main reason. I had exactly the same error! OK,
could you please do few more tests?

1) Unplug your webcam, wait for sometime then plug it back.

2) Start your Skype from console (don't run mplayer or any other
program that access webcam before these tests!)

3) Make first call using Skype

4) Make the second call using Skype

In my case, first call worked with USB audio but audio failed
from second call onward. In any case, please report
the output you get from steps (3) and (4). (May be you
could repeat these tests to ensure that there are no
transient effects!)

Cheers

[PaulluaP]

well.... it seems to work now... i found some audio volume settings
for USB webcam mic in my pulse configuration, it seems that the volume
was at level 0 :P Or it could be that i did not cleaned before
build... or not reconnected my usb cable... etc. But the source code
and patch are likely to be fine now! Even a second call does work
fine.

Hi,

It's good to hear that your USB mic is working and thanks for
checking out those patches. Restores Audio patch is aimed
to resolve "RtApiAlsa: callback thread error" that you also
had earlier. I guess, you can reproduce the error by not
applying the patch.

Cheers
Golam

[ckozler]

Thank you all for your help. I have been AFK for some time now and
not able to test this as well on my computer with the webcam. I will
do so tomorrow night and report back with some updates.

Thanks again guys.
