Author: werner
Date: 2007-10-07 15:35:06 +0200 (Sun, 07 Oct 2007)
New Revision: 3104

Added:
   developers/werner/dfu-util-r3103.patch
Log:
configure.ac: added libusbpath.a and usbpath.h dependency
src/main.c: added search filter DFU_IFF_DEVNUM (bus, devnum)
src/main.c: added pseudo search filter DFU_IFF_PATH (path)
src/main.c (get_first_dfu_device, count_dfu_devices): abstracted common code
  into iterate_dfu_devices
src/main.c (iterate_dfu_devices): added filtering by USB device number
src/main.c (resolve_device_path): new function to resolve physical USB path to
  device number suitable for filtering
src/main.c (main): new option "-p bus-port. ... .port" to specify physical USB
   path
src/main.c (main): repeat resolution after bus reset
