Logitech express Webcam issues,

GlennsPref · 07-10-2008, 10:27 PM

Hi, I'm trying to setup a web cam, first time for me with linux. The cam works OK in M$winxpsp2, but I can't seem to get it to show me a picture. Any ideas what I'm doing or not doing? Thanks in advance, Glenn

From the below info, I gather the address of the device is...
/dev/bus/usb/002/002

I installed WmWebcam and gv4l(?) (I'm using kde) and dkms-gspcav1 (but the module is already present in the kernel),

I have it sorted now, using the search function here at LQ I found this,

note, the module (gspca) is in the current mandriva kernel and loaded when the cam was plugged in, so downloading and compiling may not relevant,

This page is a bit old, but reveals other links to google, (old links)
http://www.linux.org/docs/ldp/howto/.../hardware.html

ch. 2.3.5. (of above link)

Quote:

2.3.5. Logitech (formerly Connectix) Quickcam Support

The QuickCam VC USB and parallel port model webcams are supported by the driver offered here. A kernel patch and recompile are necessary for support of this model.

The Quickcam driver is represented by two different projects that offer two different flavors of driver for certain Quickcam models, both of which are stand-alone drivers that do not require a kernel patch or recompile. The qce-ga and qc-usb drivers support the following models:

*

Logitech (earlier models of) Quickcam Express
*

Quickcam Web
*

Legocam
*

Dexxa Webcam
*

Labtec Webcam

The qc-usb driver is more experimental but reportedly works better on some models such as the Quickcam Web. Also, I have recieved correspondence that newer versions of the Logitech Quickcam Express no longer work with the above drivers; instead this page offers an experimental driver that claims to support the newer model.

Note to Redhat users: The qce-ga driver doesn't compile properly using the modified kernel source provided in Redhat 9, but a fix is available here.

Some Logitech camera models are supported by the Philips driver in Section 2.3.8.

link to qc-usb is old(moved), but I found this with google search...

now viewing with gqcam

Sorry how did you solve it ?

GlennsPref · 07-21-2008, 06:19 PM

Hi, reading through this page...
http://qce-ga.sourceforge.net/

followed this link to the download page...
http://mxhaard.free.fr/download.html

I selected the mandriva package then downloaded and installed this driver...
dkms-gspcav1-1.00.20-2mdv2008.1.noarch.rpm

The dkms.rpm and its deps. (dynamic kernel module service) is required for mandriva.

note, The source files are available here...(i did not need them)
http://mxhaard.free.fr/spca50x/Download/oldrelease/?M=D

reboot, (make sure dkms (services) is started at boot)

check the hardware is connected...

[root@GamesBox glenn]# lsusb
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 004: ID 046d:c215 Logitech, Inc.
Bus 002 Device 003: ID 046d:092f Logitech, Inc. QuickCam express Plus
Bus 002 Device 002: ID 04a9:1098 Canon, Inc.
Bus 002 Device 001: ID 0000:0000

check the module is loaded, (gspca)...

[root@GamesBox glenn]# /sbin/lsmod | grep -i usb
usb_storage 108100 0
usbhid 50400 0
ff_memless 9608 1 usbhid

usbcore 145328 8 usb_storage,gspca,usbhid,usblp,uhci_hcd,ohci_hcd,ehci_hcd
[root@GamesBox glenn]#

Even though the module is built in to the mandriva kernel, it seems the dkms is required to load the module.

Istall Gqcam and any deps...

Using Gqcam to view the image.

Hi, I have since switched to another recorder/viewer.

spcaview which is capable of recording and replaying video content with audio from the webcam.

SP54convert converts the film to standard .avi file, but I have not acheived that yet (still researching).

Perhaps because, The compression utility uses a "fourcc - DPSH" codec which I also have not been able to work.

There is also another batch of programs I am thinking about installing and trying out, uvcvideo and luvcview.

Overall, the spcaview program seems to be good, If I convert the video it will be best, and I will use it to post some vids to my blog (wip).

I have found Gideo to be a nice viewer, But I use 64bit-kde and not 32bit-gnome.

This seems to be it failing for my system, also the 64 bit OS, the libs sought for are not found by the ./configure and make processes. It seems I would require a full gnome 32bit os as well as the 64bit I have for my processor(cpu), so a bit of a mix, qt and gtk and 32bit as well as the 64bit libraries required for the system to operate. Too hard!

Installing from source in mandy-64bit is a hazardous exercise.

Cheers, Glenn.

Thanks a lot for that but I get this message :-
"Could not find a mirror from mirrorlist http://plf.zarb.org/mirrors/2008.1.i586.list"

Any idea why ?

Hi, what caused that message to pop up?

Only thing I can think of is maybe the repo is down while repopulating the packages(adding new stuff).

Try again, and you need to be root.

I think that was it the repo was down and it installed.

What is a good application to use to check if this is working. It does not seem to be working with aMSN.

I also remember renaming 2 files ...

cp /usr/lib64/libgnome-2.so.0 /usr/lib64/libgnome-1.so.0

and

cp /usr/lib64/libgnomeui-2.so.0 /usr/lib64/libgnomeui-1.so.0

to get the software to work, because of a dependency I could not resolve. The older gnome1 files were required by the software but I have gnome2 libs and I use kde. So I tried a trick, by copying and renaming the new files as the old ones.

No need to copy the files. Just symlink them.
