Hi, I'm still trying to write a webcam application for my "Creative Videoblaster Webcam Go". I have not much luck, but I accidently discovered how to cause panic with few lines of code while using ugen. Here is the code: >------------------------------------------< #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <fcntl.h> #include <dev/usb/usb.h> #include <sys/ioctl.h> #include <sys/param.h> #define DEVNAME "/dev/ugen0" static char dev_name[MAXPATHLEN]; int main(int argc, char *argv[]) { int fdout; int i; sprintf(dev_name,"%s",DEVNAME); fdout=open(dev_name, O_RDWR, 0); if (fdout<0) { perror("open"); fprintf(stderr, "Cannot open device: %s\n",DEVNAME); exit(-1); } i=0; /* PANIC here in ioctl (during second run) */ if(ioctl(fdout, USB_SET_CONFIG, &i) < 0) { perror("ioctl(USB_SET_CONFIG)"); exit(-1); } close(fdout); return 0; } >------------------------------------------< Run it once, you'll get an error. The second run will cause a panic.
