Getting Logitech camera working with Linux
Josue gave me a USB camera made by logitech - and I’ve been meaning to get it working with my Debian Lenny system for a while.
I started by plugging it in and watching syslog:
Aug 14 14:13:08 liberace kernel: [128348.749001] usb 3-1: USB disconnect, address 4 Aug 14 14:13:12 liberace kernel: [128352.657450] hub 4-0:1.0: unable to enumerate USB device on port 5 Aug 14 14:13:12 liberace kernel: [128352.894212] usb 3-1: new full speed USB device using uhci_hcd and address 5 Aug 14 14:13:13 liberace kernel: [128353.093083] usb 3-1: configuration #1 chosen from 1 choice Aug 14 14:13:13 liberace kernel: [128353.119601] usb 3-1: New USB device found, idVendor=046d, idProduct=08a9 Aug 14 14:13:13 liberace kernel: [128353.119610] usb 3-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 Aug 14 14:13:13 liberace kernel: [128353.119614] usb 3-1: Product: Camera
So far so good. I was hoping to see some reference to /dev/video, but that wasn’t part of the output and the device wasn’t created.
Next I tried:
aptitude install qc-usb-utils
Still nothing. Then, I noticed that apt-cache show qc-usb-utils says: “These programs are completely useless without a qc-usb-modules package.”
There is no qc-usb-modules package (yes, Debian seems aware of that problem).
But there is a qc-usb-source package. I installed that package and then ran:
That’s module-assistant - which makes building a kernel module a snap.
After running it, I had to do some digging to learn that the module it built is called quickcam (I tried modprobe qc-usb to no avail). The following successfully loaded the module:
0 jamie@liberace:linux$ sudo modprobe -v quickcam insmod /lib/modules/2.6.25-2-686/drivers/media/video/quickcam.ko 0 jamie@liberace:linux$
But, unplugging and re-plugging the camera produced the same output in syslog and no /dev/video.
More web searching finally turned up gspca. I removed the qc-usb modules and then:
aptitude install gspca-modules-2.6.25-2-686
modprobe -v gspca
And, to load in on my next boot:
echo "gspca" >> /etc/modules
And now, miraculously, Ekiga recognizes and uses my camera!
