troubles with my webcam and kernel 2.6.27.rc3 Msi StarCam 0xc45 0x60fc sn9c105 hv7131r with mic

Hello all

This is my first post to this list

i have troubles with my webcam and kernel 2.6.27.rc3 (Opensuse) there are modules loaded gspca sonic sn9s102
but no program sees the webcam
The webcam is Msi StarCam 0xc45 0x60fc sn9c105 hv7131r with mic

With the gspcav1 drivers compiled on kernel 2.6.25.11-0.1 (opensuse) the webcam is seen as a v4L1 webcam see log below

This webcam is handled by both the sn9c102 and gspca drivers. If the driver sn9c102 is generated, gspca does not handle it.

       [snip]

If your webcam worked with gspca v1, it should work with gspca v2. So, remove the driver sn9c102, get the last gspca v2 from

http://linuxtv.org/hg/~jfrancois/gspca/

and look at the gspca_README.txt in my page for generation and usage.

Cheers.

Hello Jean

did what say and installed all
still the webcam is nor working
none of the programs will give a picture
either no /dev/video or cant decode JPEG

recompiled the gspcav1 driver which gave in nearly every line of gspca core a error by rebooting

so i had to update opensuse 11 to get all as it was before including
the kernel
so now we have the gspcav1 driver and all the webcam programs work fine

So you can go on with the new gspca drivers for 2.6.27.xx and quite
a few webcam wont work
and most of the programs,

then i wil have this kernel and kernel sources 2.6.25 saved on dvd to be used by future versions of Opensuse
or the makefile, possible some code in gspcav1 has to be altered so we can compile it on 2.6.27

First all the computers are 64 bit opensuse 11 or mandrive 2008.2

No problem.

as i said nothing works no driver loaded
nothing to do

It is a generation problem: you did not compile with the same config as the kernel you use.

To generate, you must go to the mercurial root (<where_you_installed>/gspca-57535fa8aaff/), copy the '.config' of your kernel (usually duplicated in '/boot/config') to 'v4l/', do a
'make xxconfig' (xx depending on your taste) to add the gspca driver,
then 'make' and, as root, 'make install'.

The last command (make install) will copy all the required video modules to the /lib/modules/uname -r/ tree, including the module 'videodev' where are defined the symbols video_ioctl2, v4l_compat_ioctl32...

Indeed, if you played with your webcam before doing the make install, the old module videodev is already loaded. Then, you MUST do a rmmod of ALL the module related to video, mainly 'v4l1_compat' and 'videodev' (and the old webcam drivers).

Regards.

Jean on opensuse there is only 1 .config file and that resides in /usr/src/linux-2.6.25.11-0.1-obj/x86_64/default

there are also the Makefile modules.alias Module.symvers

all installed when i installed opensuse on that laptop normaly there is no laptop on that machine so no driver

i have tryed it one again the same result

Did you check the date of the modules in:
/lib/modules/uname -r/kernel/drivers/media/video
and:
/lib/modules/uname -r/kernel/drivers/media/video/gspca

If the dates are different, you have an install problem.

jean i come out the IT so i know my way around

I did delete everything in /ib/modules/kernelxxxxxx/drivers/video

make and make install there they were again with date of today

so i dont know what can be wrong with that

If the same date appears also in
/lib/modules/uname -r/kernel/drivers/media/video/gspca
and if you did rmmod of all the video modules before plugging the webcam, I do not see what it can be...

tonight i am with someone who has Udbuntu on his machine we will try it there
with the same webcam

Quoted 1 line

By the way this kernel has no gspca drivers at all in the kernel

Good! Thank you to give me the results.
