" Example 1: Updating a Sierra Wireless MC7354.\n"
"\n"
" The MC7354 is a 9x15 device which requires the firmware updater to specify the\n"
" firmware version string, the config version string and the carrier string, so\n"
" that they are included as identifiers of the firmware images downloaded. The\n"
" core logic in the application will try to automatically detect these strings,\n"
" although the user can also use specific options to override them or if the\n"
" automatic detection failed.\n"
"\n"
" While in normal operation, the device will expose multiple cdc-wdm ports, and\n"
" the updater application just needs one of those cdc-wdm ports to start the\n"
" operation. The user can explicitly specify the cdc-wdm port to use, or\n"
" otherwise use the generic device selection options (i.e. --busnum-devnum or\n"
" --vid-pid) to do that automatically.\n"
"\n"
" Note that the firmware for the MC7354 is usually composed of a core system image\n"
" (.cwe) and a carrier-specific image (.nvu). These two images need to be flashed\n"
" on the same operation, unless upgrading the carrier-specific image on a device\n"
" which already has the matching firmware version. The two images may be given\n"
" combined into a single image (.spk) file.\n"
"\n"
" 1a) An update operation specifying the vid:pid of the device (fails if multiple\n"
" devices with the same vid:pid are found):\n"
