Logitech -does not currently provide information for developers, but many people -have engineered several solutions for non-Microsoft use of the Color -Quickcam. - -1.1 Motivation - - I spent a number of hours trying to get my camera to work, and I -hope this document saves you some time. My camera will not work with -the 2.2.13 kernel as distributed, but with a few patches to the -module, I was able to grab some frames. See 4.0, Future Work. - - - -2.0 Compilation, Installation, and Configuration - - The c-qcam depends on parallel port support, video4linux, and the -Color Quickcam. It is also nice to have the parallel port readback -support enabled. I enabled these as modules during the kernel -configuration. The appropriate flags are: - - CONFIG_PRINTER M for lp.o, parport.o parport_pc.o modules - CONFIG_PNP_PARPORT M for autoprobe.o IEEE1284 readback module - CONFIG_PRINTER_READBACK M for parport_probe.o IEEE1284 readback module - CONFIG_VIDEO_DEV M for videodev.o video4linux module - CONFIG_VIDEO_CQCAM M for c-qcam.o Color Quickcam module - - With these flags, the kernel should compile and install the modules. -To record and monitor the compilation, I use: - - (make zlilo ; \ - make modules; \ - make modules_install ; - depmod -a ) &>log & - less log # then a capital 'F' to watch the progress - -But that is my personal preference. - -2.2 Configuration - - The configuration requires module configuration and device -configuration.

In this case, - - modprobe -v c-qcam -or - insmod -v c-qcam - - Returns a message saying "Device or resource busy" Development is -currently underway, but a workaround is to patch the module to skip -the detection code and attach to a defined port.
