Built-In Webcam Problems

[marlon89br]

I've compiled three versions: the first 5602 only, the 5602 from the SVN repository, and m5602-ov9650 from SVN. Either I get segmentation fault when modprobbing the module, or I get my webcam recognized in skype but with a black image... Is there something I can do?

Thanks for helping

The name of the file has been changed in the latest version of the driver.

Try this instead

sudo mkdir /lib/modules/`uname -r`/kernel/drivers/usb/media
sudo cp m560x.ko /lib/modules/`uname -r`/kernel/drivers/usb/media/
sudo depmod -a
sudo modprobe m560x

err hi
i am very new(2 days to be exact) to linux
i followed your guide fully
but at step 6
rd@rd-laptop:~/m5602-ov9650$ sudo mkdir /lib/modules/'uname -r'/kernel/drivers/usb/media
mkdir: cannot create directory `/lib/modules/uname -r/kernel/drivers/usb/media': No such file or directory

this message comes up
what am i doing wrong??
please help this noob
thks

Hey, all. I'm sorry, but a lot of your questions I don't know the answer to, and I'm sure your google fu is as powerful as mine.

rajan dhir, your problem seems to lie in the stupid syntaxes of bash (terminal). See,

'

is not the same as

`

. Therefore, in order to create that directory you must enter the code exactly as shown:

sudo mkdir /lib/modules/`uname -r`/kernel/drivers/usb/media

Try copy/pasting, it's easier than writing the `-symbol on a non-American keyboard.

My terminal doesn't respond when i enter lsusb | grep ALi or when I enter sudo modprobe m560x. Everything else worked perfectly.

My kernel is: uname -r
2.6.24-19-generic

Thanks,

Hello Guys,

I was folowing the instructions and I was all prepared to give a realy huge THANKS to ALL when I was right at the the end with the command

sudo modprobe m560x
FATAL: Module m560x not found.

So after a bit of hunting into what may be the problem I descovered the folowing...

davem@Dartagnon:~/m5602-ov9650$ ls /lib/modules/2.6.24-19-generic/kernel/drivers/usb/media
ls: cannot access /lib/modules/2.6.24-19-generic/kernel/drivers/usb/media/: Not a directory
davem@Dartagnon:~/m5602-ov9650$ ls -l /lib/modules/2.6.24-19-generic/kernel/drivers/usb

davem@Dartagnon:~/m5602-ov9650$

which certainly seems to confirm that problem, so I decided to see what was in this file...

davem@Dartagnon:~/m5602-ov9650$ more /lib/modules/2.6.24-19-generic/kernel/drivers/usb/media

******** /lib/modules/2.6.24-19-generic/kernel/drivers/usb/media: Not a text file ********

davem@Dartagnon:~/m5602-ov9650$

I'm not a newb, but I aint no guru.... Am I safe to "delete" this not a text file or something and if I do...what am I going to break? I'm guessing that it holds the details of the files that are loaded at start up for all the media stuff to work... or is a script that points to them?

anyone got any ideas of what I should do next??

oh by the way... I also rapidly descovered the issue of the module having changed name not very helpful!

also I've been reading that some of you have been having problems with the <lsusb> command, and "grep" the line that you are after.

If your camera is internal it may or may not be connected to a USB port.

to see if it is do this...

davem@Dartagnon:~/m5602-ov9650$ lsusb
Bus 005 Device 002: ID 0402:5602 ALi Corp. Video Camera Controller
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
davem@Dartagnon:~/m5602-ov9650$

and it will show up the ALi video controller if it is conected via that route.

OTHER wise try <lshw |grep ALi> or just plain simple lshw to see if it is there anywhere? it may be it is turned off.... in which case I can't help! sorry..

sorry if there are any funny typo's in this message, my friends young daughter is saying hi.... her first taste of Ubuntu happiness! I think I should lend her to Bill gates, so as she can prove how problematic it is having all users as default admins.... she would have destroyed my long since gone Vista partition by now

anyway I hope the above helps somewhat.

Dave

Got some trouble...

First, tanks a lot... because you've ressurrected the cam hope in my heart, also, gave me wings to fly to the solution and... but... actually stucked in the terminal after the mobprobe... oh gosh...


Seems to be the time to call it "crack in terminal"... no response...

[666porcondissaum]

Is there anybody built-in there!?

I have been trying to get my Ali 5602 cam to work these past couple of days but it just wont.

I am using ubuntu 8.10 32-bit and that may be the root of my troubles.

lsusb gives the following:

johannes@johannes-laptop:~$ lsusb | grep ALi
Bus 005 Device 002: ID 0402:5602 ALi Corp. Video Camera Controller

So I know that the cam is there and that I am using the right approach. I have tried using the approach from the original post with instructions. I have also tried to use the guide posted on the sourceforge page for the driver, but with no luck either. I have figured out that I am supposed to use the gspca_m5602 driver instead of the ov9655 one. This is easily done by replacing m5602.ko with gspc_m5602.ko in the original instructions. Everything seems to work until I hit the modprobe step.

johannes@johannes-laptop:~$ sudo modprobe gspca_m5602 
[sudo] password for johannes: 
FATAL: Error inserting gspca_m5602 (/lib/modules/2.6.27-9-generic/kernel/drivers/usb/media/gspca_m5602.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg gives this in regard to gspca_m5602

[  188.411542] gspca_m5602: disagrees about version of symbol gspca_frame_add
[  188.411563] gspca_m5602: Unknown symbol gspca_frame_add
[  188.412807] gspca_m5602: disagrees about version of symbol gspca_dev_probe
[  188.412812] gspca_m5602: Unknown symbol gspca_dev_probe
[  213.787517] gspca_m5602: disagrees about version of symbol gspca_frame_add
[  213.787534] gspca_m5602: Unknown symbol gspca_frame_add
[  213.788772] gspca_m5602: disagrees about version of symbol gspca_dev_probe
[  213.788777] gspca_m5602: Unknown symbol gspca_dev_probe

I cant get any of this to make sense because according to the sourceforge instructions, none of this is needed.

http://m560x-driver.wiki.sourceforge...l_m560x_driver

It tells me that I need livecam to get the 5602 branch to work and that is a whole different chapter.

I hope that someone out there knows what is going on and if it is even possible to get this ALi m5602 cam to work in ubuntu 8.10.
