It's supported by the gspca driver

Post:

Code:

sudo lsmod | grep gspca

If you get:

Code:

gspca_pac7311

Try switching to:

Code:

gspca_pac7302

using:

Code:

sudo rmmod gspca_pac7311

sudo modprobe gspca_pac7302

Or vice-versa

hi

l tried , here is the results

gspca_pac7311 8986 0
gspca_main 21199 1 gspca_pac7311
videodev 34361 1 gspca_main
lulzim@lulzim-desktop:~$ sudo rmmod gspca_pac7311
lulzim@lulzim-desktop:~$ sudo modprobe gspca_pac7302
FATAL: Module gspca_pac7302 not found.
lulzim@lulzim-desktop:~$ sudo rmmod gspca_pac7311
ERROR: Module gspca_pac7311 does not exist in /proc/modules

I'm not sure what's happening, seems like pac_7302 is not compiled into your kernel, it might be obsolete.

You should be able to modprobe the gspca_7311 driver out of, and back into your kernel whenever you want:

Code:

sudo rmmod gspca_pac7311

sudo modprobe gspca_pac7311

you can pass module arguments to the module through /etc/modprobe.d/[module-name]

Here is the original gspca website:

http://mxhaard.free.fr/spca5xx.html

Your camera added to the Linux kernel:

l think there is problem with ubuntu , because l am getting some errors durin startup
l will reinstall again

also l would like to ask you something else ?
How can l open iso images without cd or without copying them to cd

for examp in windows there is a software make iso ?

You can mount a *.iso image using the mount command:

Code:

sudo mount /path/to/image-name.iso -o loop /path/to/[mountpoint]

[mountpoint] can be any unused directory in your system, eg. /mnt/iso

You can make an iso image from directories and files on your computer using several programs, but all these programs control command line programs like cdrecord. If you enjoy the command line stuff then try:

Code:

man [command name]

eg:

Code:

man cdrecord
man mount
man man

The last command is the man page for the man command!

Ah! Simple mistakes:

Replace "/path/to/image-name.iso" with the path to your image.iso file
Replace "[command name]" with the command you want a manual page for... eg. "mount"
