Странная работа функции извлечения флешки

[sergey113]

Подключаю разные flash устройства и при использовании "безопасное извлечение" получаю разные странные баги. Мерцание светодиода питания или повторное подключение флешки через пару секунд.
Например флешка-картридер Kingston 2GB почему-то мерцает после извлечения светодиодом:
1 - Kingston 2GB

После повторного самопроизвольного подключения флешки отключаю ее еще раз и она больше не подключается.
Что ей надо? Куда копать?

Такая же история сейчас повторилась на ноутбуке lenovo b575e. А ubuntu теперь 14.04. Есть и отличие. Если подключать в порт 2.0, то безопасное извлечение проходит нормально. А вот если в USB 3.0 воткнуть устройство с поддержкой 3.0 (например внешний жесткий диск) , то через 1-2 секунды он сам подключается снова. С простой флешкой такого эффекта нет.
Внешний диск марки kingmax.
Думаю тут проблемы с работой демона udev.  Но возиться времени нет, надо отдавать ноутбук. Но хоть еще раз повторилась эта бяка, а то думал сам дурак Разработчики периодически совершают одни и те же оплошности.
