I found a solution on mailing-list https://lists.berlios.de/pipermail/linux-uvc-devel/ : "the only way is to reset camera, either by calling usb_reset_device() or by unplugging the cord." The USB Logitech webcams appear to have a hardware bug (something about usb timings) and as far as I understand it, there isn't a workaround for it. Unplugging the cord of my webcam I can do but I'd like to know with what command i can do a "usb_reset_device()". I guess some experts on linux-uvc are Laurent Pinchart and Evgeny.
