Acer aspire one webcam not working

STEELBAS · 2011-03-23 13:52:33

Dear all,

I'm having trouble getting the built-in camera in my Acer Aspire One (AOA110 - Ab) to work. It should be an Acer Crystal Eye camera, or a "Microdia Sonix USB" (from here)

In either case, according the Archlinux wiki (link) the uvcvideo module should make it work, and I have added it to my rc.conf.

Whenever I try to open the camera using whichever program, however, I get a message of the camera not being found. Wxcam, for instance, gives the following error:

/dev/video0: No such file or directory

lsusb also doesn't list the camera:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

And these are all the video/webcam related entries I could find in dmesg:

[    0.242888] pci 0000:00:02.0: Boot video device

[    0.264486] input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:00/input/input4
[    0.264501] ACPI: Video Device [OVGA] (multi-head: yes  rom: yes  post: no)

[    7.069685] Linux video capture interface: v2.00
[    7.136704] usbcore: registered new interface driver uvcvideo
[    7.136712] USB Video Class driver (v1.0.0)

I remember the webcam working somewhere in the past, but I can't remember when. I'm using the kernel-netbook kernel, but booting with the normal kernel doesn't seem to make any difference.

I haven't tried it with other distributions yet.

Any ideas on what could be the matter? Or any steps I could still take?

tntexplosivesltd · 2011-03-24 06:25:44

I have the D255, and the webcam works fine. I am, however, using plain old kernel26.
This is the output from dmesg | grep "video":

pci 0000:00:02.0: Boot video device
Linux video capture interface: v2.00
uvcvideo: Found UVC 1.00 device WebCam (0402:7675)
usbcore: registered new interface driver uvcvideo

I don't even have uvcvideo anywhere in my rc.conf - I've only modprobed it once.
Try doing

modprobe uvcvideo

And see if wxcam works.

Cool.

Hrm, well, this is what dmesg | grep "video" gives me:

[    0.241032] pci 0000:00:02.0: Boot video device
[    6.838193] Linux video capture interface: v2.00
[    6.936558] usbcore: registered new interface driver uvcvideo

I tried modprobe uvcvideo as my first step, but that didn't make a difference, so I added it to rc.conf to see if that would work... But no, didn't work.

Seems like the webcam isn't recognised at all Any ideas on what could be the matter?

Hrm.. Well, some more searching, but I haven't been able to find anything.
This person appears to have the same problem: http://ubuntuforums.org/showthread.php?t=1648294, but he doesn't appear to have found a solution.
I suppose my webcam could just be broken, but I would wonder how that came to be. Any more ideas? Are there any more logs that I should be checking?

Anthony Bentley · 2011-03-26 19:58:34

I have a different laptop (MSI Wind U123) whose webcam doesn’t appear in the dmesg until I hit Fn+F6 (the key is marked with a picture of a webcam). Check for a key combination like that on your laptop.

STEELBAS · 2011-03-27 11:15:25

Hmm, yes, thanks for the advice, I'd read about that before somewhere.
Unfortunately, there's no such Fn key on my keyboard, 'far as I can see:

(Not my actual laptop, unfortunately, (that white looks cool!) but the keyboard's the same.)
I've tried out all the Fn keys on the keyboard, regardless, but it doesn't appear to make any difference for lsusb

Thanks, anyway! I'm still open for other suggestions

JokerBoy · 2011-03-27 11:25:31

STEELBAS · 2011-03-27 11:27:58

Er, no, that's not what I meant. There's no Fn key for webcam on my keyboard. They're called Fn keys, I believe. I know I've got AN Fn key, don't worry.

Let me put it another way: There's no function key for the webcam on my keyboard, as far as I can see.

Aaa, sorry about that then

STEELBAS · 2011-03-27 11:32:40

Any other ideas, though?

neurolysis · 2011-04-06 16:02:57

Can reproduce. Did you ever get a solution?

STEELBAS · 2011-04-06 17:00:04

Nope, afraid not. No progress at all, to be honest. I was planning to try it out on another distro at some point, to see if that would work, but I haven't had the time so far

Anything you tried that hasn't been proposed here yet, though?

Hi, I have the same problem on my Acer Aspire 4810TZ,

on my dmesg apper:
[96013.308592] uvcvideo: Found UVC 1.00 device HD Video WebCam (064e:a133)

not make any change make a:
sudo modprobe uvcvideo
(I alredy have this on rc.conf)

sudo ls /dev/video*
ls: no se puede acceder a /dev/video*: No existe el fichero o el directorio

Previusly, on my Ubuntu this work just fine (now Im Arch user ;-) ).

yungtrizzle · 2011-05-14 00:59:14

Have you considered that its the program your using? I'm running a Acer aspire one also and no program recognizes or can use my webcam except cheese. Could possibly be a missing driver xorg driver. Notably, there's a xorg v4l driver will check that and repost

Well, I've tried Cheese, and a bunch of other programs (Guvcview, Wxcam, even Skype), and they all give the same kind of "no device found" error.

** (cheese:9949): WARNING **: cheese-window.vala:1258: Error: No device found

I was considering to test a bunch of other live-usb distros over the summer, to at least see if the webcam itself isn't broken. Let me know how that xorg driver works out, though

You should really check dmesg, from gazambuja's message the driver uvcvideo recognise the webcam but there should be a system message explaining why it doesn't create /dev/video0.

I don't think gazambuja has the same problem I have - his system does detect the webcam, which is visible in his dmesg output. My system, apparently, does not. Thanks, though

@STEELBAS, sorry I didn't read carefully enough
Your cam is not even detected by the usb system, so uvcvideo is useless.
I'm not using Arch on my AAO, but the webcam is on Bus 001 Device 002
It's the USB 2.0 bus

yungtrizzle · 2011-05-14 18:19:34

Just checked out the xorg v4l driver, it doesn't do a damn thing. Ran through some cam programs and none of them but cheese (again) recognizes or can use my webcam. I have to agree with gazambuja, it only seems to work with Ubuntu.

New drivers doesn't use v4l anymore but v4l2 system.
Camorama (and other) need to be started with the v4l1 compatibility layer (on 32 bits system) :

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so camorama

Skype for some drivers need to be started with the conversion layer :

LD_PRELOAD=/usr/lib/libv4l/v4l2covert.so skype

But anyway @STEELBAS's problems are not related to v4l2 or drivers

STEELBAS · 2011-05-15 08:29:33

Er, well, thanks, I guess

Anyone else have a clue on how I could fix this from within Arch Linux?

Stemp · 2011-05-15 10:54:04

Check usb's related messages in dmesg, maybe there is something there.
If not, you really should try a live-cd to see if you cam is not just dead (crunchbang work fine for me on my AAO)

Can't see anything that could be the webcam, really...

Edit: I just booted with the standard kernel to make sure, and the webcam is still not recognised.
The outputs for grepping dmesg with "usb" or "video" are even less filled:

$ dmesg | grep "video"
[    0.343737] pci 0000:00:02.0: Boot video device

[    3.936822] usbcore: registered new device driver usb
[    3.955698] usbcore: registered new interface driver uvcvideo

When I checked /var/dmesg.log, however, there were some more informative entries (maybe, they don't help me much):

[    0.343737] pci 0000:00:02.0: Boot video device

These entries are also present in /var/dmesg.log when booting with kernel-netbook, so there does not appear to be any different behaviour. The only difference I can see is that kernel-netbook does detect my multi-card reader.

Usb look fine, the usb 2.0 driver is loaded for the first port (ehci) where the webcam should be.
So, there is huge bug in the kernel, or, more likely, your webcam is dead.
