Ошибка com порта windows 10

Операционные системы от Майкрософт стараются нам «помочь» все больше и больше с каждым поколением.

В чем проблема: Устройство установлено, с виду все корректно, в диспетчере задач в том числе, даже работает, но сканер при этом один раз сканирует и уходит в анабиоз до ближайшего передергивания usb шнурка.

Задача тривиальная для айтишника торговой сети: организация нового кассового места с торговым оборудованием, в частности со сканером штрихкода. В качеств операционной системы — Windows 10, в качестве товарно-учетной программы используется 1С, наиболее правильный вариант вариант работы со сканерами — по com, а поскольку оборудование современное, «живых» com портов все меньше, то сканер ШК с эмуляцией com-порта. Для его работы необходим драйвер эмулятора com-порта, после установки которого в системе появляется новое устройство (фото чужое):

Но это мы видим, если ставим драйвер «руками». Если мы даем десятке поставить драйвер автоматом, то она ставит универсальный драйвер 10 версии.

Выход: отключить автоматическую установку драйверов в Windows 10 и установить насильно драйвер «USB COM Driver 6.3.0», предварительно удалив дрова, которые поставила винда и перезагрузившись.

После установки драйвера, зайти в диспетчер устройств, убедиться, что стоит нужный драйвер(не 10…, а именно 6.3)

После этого сканер начинает работать правильно
