webcam with spca5xx module not found

tur third · 07-16-2006, 02:11 PM

I have bought a Labtec webcam pro, which should be supported by spca5xx kernel module.

I had problems installing the tar file and instead installed the rpm file:

dkms-spca5xx-0.57.00-2mdk
(i'm using Mandriva 2006)

This had some dependencies which resolved themselves except for kernel source ( I did 'urpmi kernel-source' to install that)

How ever I do not know what to do next to get it to work. Can anyone help.

My lsusb is:
[root@localhost dev]# lsusb
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 046d:08a2 Logitech, Inc.
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 004: ID 06b9:4061 Alcatel Telecom Speed Touch ISDN or ADSL Modem
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

And lsmod is does not have spca5xx and when I try to add this I get:

[root@localhost dev]# modprobe spca5xx
FATAL: Module spca5xx not found.
[root@localhost dev]#

Thanks

Installing the dkms-spca5xx-0.57.00-2mdk RPM places the source for the spca5xx in /usr/src/spca5xx-0.57.00, then dkms should build it, could be it failed. I don't know if this will work but I ripped most of the commands from the rpm so it should, try running this in a shell:
dkms status -m spca5xx -v 0.57.00 2>&1 | tee -a /tmp/dkms.log
dkms add -m spca5xx -v 0.57.00 2>&1 | tee -a /tmp/dkms.log
dkms build -m spca5xx -v 0.57.00 2>&1 | tee -a /tmp/dkms.log
dkms install -m spca5xx -v 0.57.00 2>&1 | tee -a /tmp/dkms.log
then post /tmp/dkms.log.

Thanks for the help unSpawn! This has enabled me to see the error of my ways. I did as you suggested and ran the dkms commands. Running 'dkms build' told me that I did not have the kernel source installed. (not sure what went wrong there).

Code:

Error! Your kernel source for kernel 2.6.12-12mdk cannot be found at
/lib/modules/2.6.12-12mdk/build or /lib/modules/2.6.12-12mdk/source.
You can use the --kernelsourcedir option to tell DKMS where it's located.

I downloaded the right kernel source rpm, being one for '2.6.12-12'. This put the source in the required directories.

I then completed the dkms commands, and typed

Code:

modprobe spca5xx

lsmod now shows

Code:

spca5xx               342160  0
videodev                7104  1 spca5xx

Then configured GnomeMeeting, and am now looking at a picture of myself!

Thanks again for your help.

Hello,

I am in a similar situation with Mandriva 2006. The only difference is that I am using the Logitech Quickcam IM (046d:08d9).

I have installed properly the spca50xx driver which is known to work for this webcam.

My problem with Mandriva is that the webcam is recognized by udev as a audio device. Then obviously having the right driver does not help !
I guess the udev config needs to be changed in order to load the right modules and create /dev/video !

Below you will find the /var/log/messages part generated when I plug it in.

Many thanks for your help.

Does spca50xx appear in the list of modules added to your kernel when you type:

lsmod

Hi,

I solved that problem over the weekend but did not have time to post my solution.

So what did I do ?
- I uninstalled the rpm dkms-spca5xx-0.57.00-2mdk (this needs to be done first with dkms and then rpm).
- I downloaded the tarball of spca5xx
- Complied and installed it as instructed.
- performed the modprobe and added the alias in modules.conf

Now the webcam works as designed. I still have the error message : "udev[4470]: run_program: exec of program failed" but that does not seem to bother the system more than that.

Thus I guess that something is wrong in the dkms package of spca5xx for Mandriva 2006 and that udev also has some problems left.

I hope this helps others.
