Logitech Quickcam Express USB webcam (0x46d/0x920) working under Linux (sort of)

Some notes on trying to get a Logitech Quickcam Express USB webcam (device ID 0x46d/0x920) to work under Linux.

This is page is mainly to provide a link to the correct driver for anyone Googling for the device ID (as I did).

So far (March 2005) the performance is not too excited: just as stated on the driver home page. The developers also state they have had no help from the manufactures :-(

Display Notes

I bought my Webcam in December 2004 from a large department store in Germany. It is a simple Quickcam Express, but could be referred to in Dec 2004 as the "new type" (see driver section below).


You need this s/w installed:

What I have


1: Configure and build the kernel

(If you do not build your own kernel the correct modules may already be available: skip this step and see what happens.)

You may have to check the exact kernel options required: I already had USB support compiled in, but I did add CONFIG_VIDEO_DEV and CONFIG_VIDEO_PROC_FS (25/03/05 for kernel 2.6.10 only CONFIG_VIDEO_DEV).

If you at least have USB support available you can plug the Webcam in: this should show the device ID (0xHHH/0xHHH) in the system log which can then be used to determine which driver is required.

FAILED: I first tried the QuickCam Express Driver http://sourceforge.net/projects/qce-ga which did not recognise the device ID. This is when I discovered that mine is a "new" type QuickCam Express (different sensor chip).

FAILED: So I tried http://home.tiscali.dk/tomasgc/labtec/ that claimed support for this device ID. I got the latest stable, 0.3 and it recognised the webcam OK: "hub.c: new USB device 00:07.2-2.2, assigned address 6" (the README does not list the device but this is incorrect !). This has now merged into the spca5xx driver.

Current (25/03/05): http://mxhaard.free.fr/download.html spca5xx driver project, latest is "0.560315 19/03/2005" and supports 2.4 and 2.6 kernels. My device ID is now listed in the README.

Result (25/03/05):

/dev/video0 (symlink to v4l/video0)

Gentoo-portage spca5xx 22/05/05 I notice that the driver now in Gentoo portage but even the masked version is 20050328 (1 behind).
