У меня есть красивая древняя эргономичная клавиатура (без названия SK - 6000), подключенная через переходник DIN-> PS /2 к адаптеру USB /PS /2-> к моей док-станции. После Grub перестает работать. Требуется либо приостановка и пробуждение, либо повторное подключение, когда Linux работает, чтобы заставить его работать. Никаких дополнительных модулей ядра не загружается для этого. Когда это работает, и я перезагружаюсь без выключения, это будет работать немедленно.
Даже когда он не работает, он виден (номер устройства lsusb различается, но вывод одинаковый независимо от того, работает он или нет):

При повторном подключении dmesg показывает это (которое, за исключением 1-й строки и других входных номеров, уже появилось во время загрузки):

Более поздние строки звучат так, как будто они уже есть. И ни один из них не будит клавиатуру:

$ sudo udevadm trigger
Я также попробовал это безрезультатно:
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/bind
ksh: echo: write to 1 failed [No such device]
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/unbind
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/bind
# echo usb1 >/sys/bus/usb/drivers/usb/unbind
# echo usb1 >/sys/bus/usb/drivers/usb/bind
Что еще я должен попытаться получить такой же результат, как повторное включение или приостановка, просто введя команду?
