Title: Webcam device not found (old Acer Travelmate with USB Live! Cam)
Post by: Marco Tucci on May 01, 2020, 09:20:32 AM
Hello,

I have recently istalled Linux Lite on an old Acer Travelmate and it works really nicely.

I am now trying to connect webcam (Creative Live! Cam) via USB but neither Camorama nor Guvcview can detect any cameras.

Here is the outcome of 'lsusb'
Bus 001 Device 008: ID 041e:4045 Creative Technology, Ltd Live! Cam Voice
Bus 001 Device 007: ID 041e:4048 Creative Technology, Ltd
Bus 001 Device 006: ID 041e:404b Creative Technology, Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 046d:c03d Logitech, Inc. M-BT96a Pilot Optical Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

thanks to anyone could help me!
kindest regards from Marco.

hi, perhaps I have been unclear on what I am asking.

I am now stuck with error message
    GUVCVIEW ERROR
    NO VIDEO DEVICE FOUND

(similar errors from Camorama and others)

What should I do now?
thanks again; Marco.

Have you tried Cheese?

sudo apt-get install cheese

sudo apt-get install cheese

yes and I get the same error message "no device found" :-(

How can I check if the device driver is running properly?

Thank you, DeepThought,
problem is that when I run "ls /dev/video*", I get the error
    ls: cannot access '/dev/video*': No such file or directory

which makes me think that I have a more basic problem with device driver perhaps?

It seems that Ubuntu recognizes the webcam and initiates its sound hardware correctly. The following commands might solve the problem with video hardware initialization.

1. Open a terminal (Ctrl+Alt+T)

2. Enter the following command to stop linux webcam driver,
$ sudo rmmod uvcvideo

3. Enter the following command to restart the driver,
$ sudo modprobe uvcvideo

4. Now test your webcam with the Skype in Ubuntu. If it works fine, please let me know.

Good luck!

That is the last post in the thread so the op either solved it or gave up :)
Worth a try :)

Tried that one too, no success.

I think the problem is deeper, please have a look at the output of command "ls /dev/video*"
Code: [Select]
> ls /dev/video*
ls: cannot access '/dev/video*': No such file or directory

Doesn't look to be supported in Linux. Get yourself a cheap Logitech, they're mostly all supported.

thanks for your support anyhow!
should I mark this thread as "solved" or "abandoned"?

Solved, as there is a definitive answer.
