Hi, Other traces when trying to use luvcview: uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_read: not implemented. uvcvideo: uvc_v4l2_release uvcvideo: uvc_v4l2_open uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QUERYCAP, dir=r- (0x80685600) uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_S_FMT, dir=rw (0xc0d05605) uvcvideo: Trying format 0x47504a4d (MJPG): 320x240. uvcvideo: Using default frame interval 33333.3 us (30.0 fps). uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_S_PARM, dir=rw (0xc0cc5616) uvcvideo: Setting frame interval to 1/15 (666666). uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_REQBUFS, dir=rw (0xc0145608) uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QUERYBUF, dir=rw (0xc0585609) uvcvideo: uvc_v4l2_mmap uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QUERYBUF, dir=rw (0xc0585609) uvcvideo: uvc_v4l2_mmap uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QUERYBUF, dir=rw (0xc0585609) uvcvideo: uvc_v4l2_mmap uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QUERYBUF, dir=rw (0xc0585609) uvcvideo: uvc_v4l2_mmap uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QBUF, dir=rw (0xc058560f) uvcvideo: Queuing buffer 0. uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QBUF, dir=rw (0xc058560f) uvcvideo: Queuing buffer 1. uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QBUF, dir=rw (0xc058560f) uvcvideo: Queuing buffer 2. uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_QBUF, dir=rw (0xc058560f) uvcvideo: Queuing buffer 3. uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_STREAMON, dir=-w (0x40045612) uvcvideo: uvc_v4l2_ioctl v4l2 ioctl VIDIOC_DQBUF, dir=rw (0xc0585611) uvcvideo: Dequeuing buffer 0.
Before the "uvcvideo: uvc_v4l2_release" line, it was when I was trying to use the cam with kopete. Another question, when I do a lsmod | grep uvcvideo I have : uvcvideo 53508 1 compat_ioctl32 17217 1 uvcvideo videodev 36673 2 uvcvideo v4l1_compat 20549 2 uvcvideo,videodev v4l2_common 28353 3 uvcvideo,compat_ioctl32,videodev Reading some web stuff, I showed that there was an 'usbcore' module but if I try to load it it send an error because it is not found.. Does uvcvideo needs the usbcore module?
