hi,
i am testing UVC WebCam with bf533-ezkit, my USB hos is ISP1362, the kernel is 2.6 28(have V4l2 UVC driver),and with some forum friends's help now can open device,but i come to another problem. the code snippets is here:
static int video_enable(struct vdIn *vd)
{
int type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
int ret;
ret = ioctl(vd->fd, VIDIOC_STREAMON, &type);
if (ret < 0) {
perror("Unable to start capture");
return ret;
}
vd->isstreaming = 1;
return 0;
}
the error message in the console is :
uvcvideo: Failed to submit URB 0 (-28).
Unable to start capture: No space left on device
the ioctl above control to start video capture ,it is the part of driver,so i don't know what will the problem. Is the USB HCD driver problem? it seem can detect my device well and can read PID,VID.
Also my WebCam can work 30 fps(frame per sec),but in my code used ioctl to configure the fps,it unsuccess.
Dose someone have done same work can give some help?

we dont maintain any USB host controller driver, so really you should ask the vendor, or perhaps the general usb mailing list
