ps / 2-> usbキーボードをLinuxに接続しますか？

私は、DIN-> ps/2アダプターを介してドッキングステーションのps/2-> usbアダプターに接続された、素敵な古代の人間工学に基づいたキーボード（SK-6000という名前はありません）を持っています。 Grubの後、動作を停止します。 Linuxの実行中に、サスペンドしてウェイクアップするか、プラグを再接続する必要があります。このために追加のカーネルモジュールがロードされることはありません。それが機能し、電源を切らずに再起動すると、すぐに機能します。

でも ない 動作し、表示されます（lsusbデバイス番号は異なりますが、動作しているかどうかに関係なく出力は同じです）：

後の行はすでにそこにあるように聞こえます。そして、これらのどれもキーボードを目覚めさせません：

$ Sudo udevadm trigger

私もこれを無駄に試しました：

# 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

コマンドを発行するだけで、再接続または一時停止と同じ結果を得るために他に何を試みる必要がありますか？

ここで解決策： https://askubuntu.com/questions/48792/how-to-enable-an-extern-keyboard-using-ps2-to-usb-adapter-on-a-notebook

このアダプタには2種類あります。1つはプラグを別のプラグに変更するだけで、もう1つは信号を処理します。

私も同じ問題に直面していました。

解決策（根本的な原因はわかりませんが、これは私にとってはうまくいきました）：

  1. PS2からUSBをラップトップから取り外します。
  2. キーボードとマウスを取り外します。
  3. PS2-to-USBをラップトップに接続し直してから、キーボードとマウスを接続するだけです。動作を開始します。根本的な原因は不明です。
