I cannot seem to get anywhere with the pwc driver. Whatever I do I get a "Broken Pipe" message. This is SuSE-10 OSS on an Athlon XP2000 system v4l-conf -c /dev/video1 v4l-conf: using X11 display :0.0 dga: version 2.0 mode: 1280x1024, depth=24, bpp=32, bpl=5120, base=0xd0000000 can't open /dev/video1: Broken pipe dmesg has this: pwc >> video_open called(vdev = 0xec540260). pwc Failed to set LED on/off time. pwc type = 740 pwc >> pwc_allocate_buffers(pdev = 0xec229400) pwc Allocated image buffer at f2901000. pwc << pwc_allocate_buffers() pwc type = 740 pwc set_video_mode(176x144 @ 10, palette 15). pwc decode_size = 1. pwc Using alternate setting 1. pwc Failed to set video mode QSIF@10 fps; return code = -32 pwc First attempt at set_video_mode failed. pwc set_video_mode(160x120 @ 10, palette 15). pwc decode_size = 1. pwc Using alternate setting 1. pwc Failed to set video mode QSIF@10 fps; return code = -32 pwc Second attempt at set_video_mode failed. That -32 is EPIPE (broken pipe) /dev/video1 is owned by me in the video group and is a logitech 4000 Pro. The latest driver from Saillard.org doesn't change this problem Has anybody had this problem and found a cure? I cannot find anything that helps on this list's archives, or by googling Geoff
