Usb disconnect windows 10

Вариант 1: Использование USB-хабов

Если для подключения USB-устройства используется переходник или разветвитель, подключите устройство напрямую и понаблюдайте за ним, — возможно, все дело в USB-хабе. Надо сказать, использование дешевых переходников является одной из самых распространенных причин отключения USB – в таких случаях рекомендуется либо подключать конечное устройство непосредственно в порт, либо использовать активные USB-концентраторы, то есть переходники с автономным питанием. Также, если проблема возникла на десктопном компьютере, есть смысл попробовать подключить USB-устройства не к передней, а к задней панели системного блока.

Вариант 2: Нехватка мощности порта

Если отключаются только некоторые устройства, например мышки, клавиатуры, мобильные телефоны в режиме зарядки и беспроводные адаптеры, но при этом продолжают работать флешки, это может указывать на невозможность обеспечения USB-портом достаточной мощности. Вероятнее всего, проблема вызвана аппаратными неисправностями, но окончательно установить факт поломки можно лишь в сервисном центре.

Среди наиболее распространенных аппаратных неполадок отмечаются повреждение кабелей и разъемов, неисправности цепи питания на самой материнской плате, замыкания на корпусе. В ряде ситуаций отваливание USB-портов является следствием другой аппаратной проблемы – неисправности или деградации блока питания. На последнее будут указывать такие характерные симптомы, как внезапное отключение компьютера при повышении нагрузки на графическую подсистему и периодическое включение компьютера не с первого раза.

Вариант 3: Электропитание устройств

При соответствующих настройках электропитания Windows 10 может отключать USB-устройства с целью экономии заряда аккумулятора. Проверьте эти настройки.

1. Откройте «Диспетчер устройств» из контекстного меню кнопки «Пуск».

2. Найдите в списке периодически отключающееся USB-устройство и откройте его «Свойства» двойным по нему кликом или из контекстного меню. Использующие интерфейс USB-устройства могут находиться в разделах «Мыши и иные указывающие устройства», «Контроллеры USB», «Контроллеры запоминающих устройств» и «Устройства HID».

3. В окне «Свойств» устройства переключитесь на вкладку «Управление электропитанием» и снимите, если установлен, флажок «Разрешить отключение этого устройства для экономии энергии». Сохраните настройки.

Если в «Свойствах» ряда устройств вкладка «Управление электропитанием» отсутствует, тогда ничего предпринимать не нужно.

Общие настройки электропитания

Если предыдущий способ не помог или в «Свойствах» устройства отсутствует вкладка «Управление электропитанием», деактивируйте функцию временного отключения USB в дополнительных настройках электропитания.

1. Откройте дополнительные настройки электропитания, выполнив в вызванном нажатием клавиш Win + R диалоговом окошке быстрого запуска команду control.exe powercfg.cpl,,3,.

2. Найдите и разверните в списке раздел «Параметры USB», выделите настройку «Параметр временного отключения USB портов» и установите для нее значение «Запрещено». Для ноутбука меняйте значения в подразделах «От батареи» и «От сети». Сохраните настройки.

Вариант 4: Проблемы с драйверами

Причиной обозначенной проблемы может стать неправильная работа драйверов. Эта неполадка не является типичной, но исключать ее не следует. Для начала попробуйте переустановить неправильно работающее USB-устройство.

1. Откройте «Диспетчер устройств», отыщите в списке проблемный USB-девайс, кликните по нему правой кнопкой мыши и выберите из контекстного меню «Удалить устройство».


Картинка с сайта: lumpics.ru

2. Подтвердите удаление. Если в диалоговом окошке будет предложено удалить драйвера устройства, дайте на это свое согласие.
3. Вытащите устройство из порта, а затем подключите его заново. Устройство будет переустановлено.

Можно пойти и более радикальным путем – удалить в «Диспетчере устройств» все устройства USB (включая концентраторы), а затем перезагрузить компьютер.

Сторонние приложения

Отмечены также случаи, когда нестабильность работы USB вызывалась конфликтом их старых и новых драйверов. В этом случае решением может стать удаление из системы старых драйверов ранее подключавшихся к компьютеру устройств USB средствами утилиты USBDeview.

1. Скачайте с сайта разработчика бесплатную портативную утилиту USBDeview и запустите ее от имени администратора.

   Скачать USBDeview с официального сайта

2. Запустите утилиту от имени администратора, найдите в списке проблемное устройство, выделите его мышкой и нажмите кнопку с изображением корзины, чтобы удалить из системы соответствующий драйвер.


Картинка с сайта: lumpics.ru

3. Перезагрузите компьютер.

Главная трудность при работе с USBDeview заключается в правильном определении USB-устройства. Чтобы его определить, нужно смотреть не только на название, но также на описание, тип и статус. Подключенные активные устройства в приложении отмечены зеленым маркером, отключенные – серым.

Если проделанные манипуляции не принесут положительного результата, скачайте с сайта производителя материнской платы оригинальные драйверы чипсета южного и северного мостов и установите их. При затруднении с выбором драйверов воспользуйтесь Driver Booster или аналогичной сторонней программой для автоматического поиска и обновления драйверов.
