220 | * in --scan output which matches the vendor's gf(1) utility. | |
221 | * This version detail is _not_ checked against conn= specs | |
222 | * because users may specify the longer text string with | |
223 | * more leading digits from lsusb(8) output. That test would | |
224 | * fail when executed against the shorter firmware output. | |
