Дальше вопрос - либо сносить подключенный порт из списка и возвращать список, либо
менеджер сам по пришествии сигнала от того девайса, который сейчас в активном поиске,
выведет ошибку (если не нашёлся), а если нашёлся, то перед подачей списка другому устройству
сам посносит оттуда порты подключенных устройств.
УПРТСТЬ!!!!!!Ё!!!!Омск!!!!!
Важный момент! до тех пор пока не случилось коннекта или дисконнекта, менеджер не
должен разрешать поиск порта, не то конфликт и ужос. 13 портов тестятся 40 сек, не менее!
