Unknown USB Camera : How do I make it work ?

koodoo · 06-18-2005, 10:20 PM

Hi I am currently working on Slackware 10.0.

Now, I have a USB Camera which I got from a friend. This camera does not have any identification mark or vendor symbol on it, so I do not know which brand it is?

How do I make it work?
At present I know only how to plug it into a USB port and after that I am clueless of what to do.

Can I gather the vendor information and other hardware details for this cam. by plugging it in and then issuing some commands?

Please help, I am a complete n00b in this respect.

Thanks in anticipation.

After you plugin the camera, in a term issue "dmesg" for information as to what the kernel
did with the device. If you see something like

Code:

usb 5-2: new full speed USB device using uhci_hcd and address 3
scsi2 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning

Attached scsi generic sg1 at scsi2, channel 0, id 0, lun 0,  type 0
usb-storage: device scan complete

you should have all the information you need.

Be reading that you can see that my Sony DSC was mounted at /dev/sdb1,
so I will mount it by issuing "mount /mnt/sdb1" according to the way I have
setup "/etc/fstab" and this will be the results of mounting it

Code:

mingdao@james:~$ mount /mnt/sdb1
mingdao@james:~$ ls -alh /mnt/sdb1
total 16K
drwxrwxrwx   2 mingdao users 16K 1970-01-01 07:00 ./
drwxr-xr-x  10 root    root  240 2005-04-04 04:53 ../
-r-xr-xr-x   1 mingdao users   0 2003-11-28 01:54 memstick.ind*
mingdao@james:~$

This is my /etc/fstab file

Code:

I hope most of that is self-explanatory, and if not you might want to read
"man fstab" and "man mount" then post back with questions.

Hi thanks for the quick reply. I just want to ask that after plugging in the CAM I have to restart the system before issuing the dmseg command. Is there a way to make it work without rebooting.

I'll just reboot the system and then post back the result.
Thanks again.

Bruce Hill · 06-18-2005, 10:48 PM

You are running Linux, not Windoze. There is no need to reboot the system unless you
recompile and install a new kernel, or make a hardware change. You should plug in the
camera, open a terminal, and issue "dmesg" as a normal user.

koodoo · 06-18-2005, 11:06 PM

Sorry about that. I thought I had to reboot coz I did not think that the kernel would detect the USB device as soon as I plug it in.

Here's the output of the dmesg command :

You only need to plug in the camera, open a terminal, and issue "dmesg" to
get the information. If you have USB mass storage support, it should work.
If not, then you will have to recompile your kernel. Just try to plug the camera
in and then issue "dmesg" -- you should have it in less than 30 seconds.
Post whatever it says here, and can you use any other USB storage device?

koodoo · 06-25-2005, 06:14 AM

Hi, I've already posted the output of the dmesg command after plugging in the camera in the previous post.

Also Slackware 10.0 have some hotplug service which deals with auto-detecting usb devices at boot time. Here is the output of dmesg after starting the hotplug service.

As far as using any other usb storage device, I do not have one right now so I cannot test it but I guess that the 2.4.26 kernel supports this.
I remember that in Fedora Core 1, I could easily use pen drives. It was some kernel no. 2.4.22

Thanks in anticipation.

Bruce Hill · 06-25-2005, 09:13 AM

Sorry for confusing you. Let's do it this way:

(1) boot your Slackware system, without the camera plugged in
(2) open a terminal
(3) issue dmesg, and notice the last few lines
(4) plug in the camera, and wait 30 seconds
(5) in the terminal, issue dmesg again
(6) post just the changes in dmesg after step 3

If you don't have something like "usb-storage: device scan complete"
at the end of the dmesg output, but you do have some new output,
then perhaps you should wait a little longer until there's nothing new.

You don't need to manually start hotplug, unless you don't have it
starting by default when you boot the comp. If not, and you would
like it to start, just issue as root "chmod a+x /etc/rc.d/rc.hotplug"
and if you don't know if it starts at boot or not, then issue
"ls -l /etc/rc.d/rc.hotplug" as user and post that output.

Hi, sorry for replying very late and sorry for being such a nuisance.

I understand what you say and followed your algorithm.
First I booted the computer without the camera plugged in.
Then I opened a terminal and issued the dmesg command.

I then plugged in the camera, waited for about 2 minutes and then again issued the dmesg command.
I did not notice any difference in the output of the command in the two cases. I even compared it line by line and they were exactly the same!!!!

I then removed the camera and plugged it in another USB port and issued the dmesg command again, but again I got exactly the same output.

So, it seems that something somewhere maybe dead.
Any ideas??

Also I myself have disabled the hotplug service at bootup because it took some time to start and slowed the booting process. Also I do not think that I should have the hotplug service running inorder to access USB devices (or do I ?).

Thanks in anticipation.

Bruce Hill · 06-28-2005, 12:19 AM

Yes, you need the hotplug service running. From "man hotplug"

Quote:

hotplug is a program which is used by the kernel to notify user mode software
when some significant (usually hardware-related) events take place. An example
is when a USB or Cardbus device has just been plugged in. This is useful for
automatically loading and setting up drivers, packaged either as kernel module
or as user mode programs.

You can disable hotplug and do other things to get your devices
recognized, but I wouldn't recommend it at this time. With Linux
you rarely need to reboot...only when you recompile the kernel
or add/remove a piece of hardware. And hotplug doesn't add
more than 15 seconds or so to your boot, compared to how long
would you leave the computer running once it's up? You're not
going to get that device working without hotplug at this stage,
so whatever you did to stop it, start it again. And it would be good
for you to reboot now, with hotplug running. Then try it again...

If you don't know how you stopped hotplug, post back and I'll
tell you how, what, and where to check.

You are not a nuisance IMO as long as you try reading and learn
some things on your own, also. If we didn't want to help you, we
wouldn't come to LQ. Well, there are the occassional trolls. :)

Let's get this working, then we'll speed up your boot time later.

koodoo · 06-28-2005, 07:09 PM

Hi, thanks for the reply.

I enabled the hotplug service to start at boot time.

Then I rebooted the computer (this time with the hotplug service starting at boot time)

I issued the dmesg command and noted its output.
Then I plugged in the camera, waited for about 2 minutes, again issued the dmesg command and noted its output.

The only difference in this case was the addition of these two lines :

Code:

hub.c: new USB device 00:1d.0-1, assigned address 2
usb.c: USB device 2 (vend/prod 0xc45/0x6029) is not claimed by any active driver.

Thanks again.

Hi Sir,

Thanks for the reply.
I am extremely sorry for not having replied to your post as I had gone to a far off place on vacation for over a month. So I couldn't get access to the Internet for that period.

I'll try and see if I can make something of the links you provided.

Thanks again for the help.
