This is something to be expected, given libghoto2 explicitely asks libusbx to enable debugging output in libgphoto2_port/libusb1/libusb1.c: | static int gp_port_usb_init (GPPort *port) | { | port->pl = malloc (sizeof (GPPortPrivateLibrary)); | if (!port->pl) | return (GP_ERROR_NO_MEMORY); | memset (port->pl, 0, sizeof (GPPortPrivateLibrary)); | | port->pl->config = port->pl->interface = port->pl->altsetting = -1; | | libusb_init (&port->pl->ctx); | libusb_set_debug (port->pl->ctx, 255); | ... -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
