It's calls to usb_function_active() and usb_function_deactivate() are unbalanced. Do you have any other changes to g_webcam? Also, uvc-gadget.git doesn't compile, had to modify it a bit: -#include "../drivers/usb/gadget/uvc.h" +#include "../drivers/usb/gadget/function/uvc.h" Also fixed a build warning: @@ -732,6 +732,8 @@ int main(int argc, char *argv[]) fd_set wfds = fds; ret = select(dev->fd + 1, NULL, &wfds, &efds, NULL); + if (ret < 0) + return ret; if (FD_ISSET(dev->fd, &efds)) uvc_events_process(dev); if (FD_ISSET(dev->fd, &wfds)) Laurent, have you tested g_webcam recently? What's the magic to get it working?
