I just backed out gspcav1 and compiled all the kernel drivers as modules and just plugged the webcam in; the kernel works out which ones to use. # lsmod | grep spca gspca 621584 0 gspca_zc3xx 48320 0 gspca_main 22656 1 gspca_zc3xx compat_ioctl32 8256 2 gspca,gspca_main videodev 34112 3 gspca,gspca_main,compat_ioctl32 However, you are not out of the woods yet! You will probably need the libv4l libraries installed to get spcaview to work. Skype and kopete still completely fail to find the camera. :( There is a long thread on the Gentoo fora about this. -- ------------------------------------------------------ Robin Atwood
