Logitech Quickcam Zoom - using an old webcam in 2020

Postby Lysander » 2020-06-15 11:10

This is an old webcam, purchased in 2003, so it's probably too much to ask for it work in 2020?

When plugged in via USB the green light comes on so there is some life, and hwinfo gives

However, when using Cheese or guvcview I just get a notification that no device is detected. Is it possible to get this thing working in Debian 10 or should I buy something more modern?

Your webcam is officially supported by the pwc driver, but see this:
Logitech QuickCam Zoom (On some webcam likes Quickcam Zoom Silver (usb product ID: 046d:08b4), you need to set module option: power_save=1 )

@ oswaldkelso: I'm assuming that the driver is already installed, see this:

Code: Select all
Driver Info #0:
    Driver Status: pwc is active
    Driver Activation Cmd: "modprobe pwc"

This is the first time I've added a module option to the kernel, will have to read up on how to do this.

Thanks HoaS, so I presume it's just

Code: Select all
#modprobe pwc power_save=1


Though I am still not getting any visuals from the camera in guvcview or Cheese.

Code: Select all
pwc --version
whereis pwc
find pwc


All come back with nothing.

Code: Select all
lysander@psychopig-xxxvii:~$ dpkg -s pwc
dpkg-query: package 'pwc' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files.

Only if the module wasn't loaded beforehand.

Check the actual value by examining the content of /sys/module/pwc/parameters/power_save

So I am 50% of the way there - I can record audio but no video. I am kind of at a lost of what to do next. Does anyone have any ideas?

pwc is loaded properly

Code: Select all
lysander@psychopig-xxxvii:~$ cat /sys/module/pwc/parameters/power_save

What is the dmesg showing after modprobe-ing the pwc module?

I would also try something other than cheese to try narrow down the issue.

ffmpeg or mpv

https://trac.ffmpeg.org/wiki/Capture/Webcam

Like wise try something like setpwc to see if it gives a clue

It only in the archives if you want to try a deb
http://ftp.ticklers.org/debian-archive/ ... /s/setpwc/

newer version here but no deb
