اولا ما مخلص هرچی سید بزرگواره هستیم
دوما دوست عزیز من فکر میکنم تمام اون صفحه یه روش رو داره میگه که با دستورات خاصی در محیط ترمینال از یه ابتدا تا یک انتها مرحله به مرحله باید رفت جلو!
$ lsusb
Bus 001 Device 005: ID 2770:9120 NHJ, Ltd Che-ez! Snap / iClick Tiny VGA Digital Camera
Then this guide is for you!
ATTENTION: If you tried any other methods before this one to get your webcam to work and you had no success, please check the last part of this howto, marked with a
Pre-requisites:
gcc, make and cvs
Code:
$ sudo apt-get install gcc make cvs
These were the steps I followed:
First: Get the source files for your webcam. These will be used to create the module to recognize your cam.
This command will download some files to a directory called 'sqcam26' inside the current directory.
Code:
$ cvs -z3 -d:pserver:anonymous@sqcam.cvs.sourceforge.net:/cvsroot/sqcam co -P sqcam26
$ cd sqcam26
Now, to compile this without errors, type (you may replace 'gedit' with your text editor of choice. Say, 'vim'):
Code:
$ gedit Makefile
Edit this file's 6th line. It should be like this:
Code:
KERNEL_DIR := /lib/modules/`uname -r`/build
Save and exit
Now, we must edit another file (again, 'gedit' can be replaced by your favourite editor):
Code:
$ gedit sq905.c
Scroll down to line 1183 and add these dashes to these lines:
Code:
while (size > 0) {
page = usbvideo_kvirt_to_pa(pos);
//#ifdef HAS_REMAP_PAGE_RANGE
// if (remap_page_range(vma, start, page, PAGE_SIZE,
// PAGE_SHARED)) {
//#else
if (remap_pfn_range(vma, start, page >> PAGE_SHIFT, PAGE_SIZE,
PAGE_SHARED)) {
//#endif
up(&cam->busy_lock);
return -EAGAIN;
}
This is the part of the code which produces errors when trying to compile using the current version (as of May 7th 2007). As so, we have to correct it manually.
Adding these dashes is called "commenting". We are excluding these lines from being interpreted, as they produce errors while creating the module. This is possible to do because the new kernels do not have those instructions and that piece of code gets unnecessary and as so, can be excluded.
VERY IMPORTANT Only add those "//"s and NOTHING else!!! You are warned.
Save and exit
_________________________
NOTE ONLY for users of newer versions of Ubuntu than Dapper Drake or other Linux distributions with kernel equal or superior to 2.6.17 If anyone using an older kernel is having any of the problems described here or here, please tell me:
There are some more things you will need to do:
Keep editing sq905.c and scroll down to line 1228. Comment that one too.
Code:
// .owner = THIS_MODULE,
Now you can save that file and exit.
Now we must edit another file: usbvideo.h:
Code:
$ gedit usbvideo.h
Add this last line after the other "#include" lines:
Code:
//#include <linux/config.h>
#include <linux/videodev.h>
#include <linux/usb.h>
#include <media/v4l2-dev.h>
Also, notice that the #include <linux/config.h> line must be commented.
Save and exit

All users continue here:
There is an alternative method to do all of these steps in a simple one:
Download this post's attachment with name sqcam26.tar.gz and then type:
Code:
$ tar -xvzf sqcam26.tar.gz
$ cd sqcam26
If (and only if) you are using a newer version of Ubuntu or a distribution with a newer kernel than 2.6.17, you will need the attachment named: sqcam26-new.tar.gz.
________
All you have to do now is this:
Code:
$ make gamma.h
$ make
$ sudo mkdir /lib/modules/`uname -r`/kernel/drivers/usb/media
$ sudo make install
$ sudo depmod -a
$ sudo modprobe sqcam
The 'make' command will output some warnings. It is important to note that these are just warnings, not errors and so let's hope it isn't anything too bad.
And to check that the camera is working:
Code:
$ sudo apt-get install xawtv
$ xawtv
This program seems to be able to record video (and simultaneous audio, if you have a microphone). Anyway, I haven't been able to check it, as I seem to not have the necessary codecs to play it. If anyone can see the recorded videos, please say something.
If you see some messages saying "Device or resource busy" and you can't see anything from your camera, you may need to restart your computer. (just type 'xawtv' from a console to check it again after you restarted)
After all this, you must now be able to see video from your webcam!
To use your webcam with aMSN, you will just have to go to Preferences -> Others and run the Video Wizard. There, choose from one of the 'devices' and 'channels'. For me, the channel "Bayer Grid 1" worked well. All others show messy images with strange colors. Sometimes, you will need to cancel the wizard and restart it, but after two or so retries I could always get a nice picture of my room.

WARNING FOR PEOPLE WHO HAVE TRIED TO INSTALL THIS WEBCAM THROUGH EASYCAM, EASYCAM2 or using the sources for sqcam without correcting the sourcefiles:
If you used any of these methods, you will create modules which can cause errors while trying to install, rendering your webcam unusable.
Before following this HOWTO's steps, do this:
Code:
$ sudo updatedb #this command may take some time to finish
$ locate sqcam.ko
Now, for every line you see on this command's output, you will have to remove that file. e.g.:
If this was in the output
Code:
/lib/modules/2.6.15-28-686/kernel/drivers/usb/media-back/sqcam.ko
You will have to do:
Code:
sudo rm /lib/modules/2.6.15-28-686/kernel/drivers/usb/media-back/sqcam.ko
