lspci私はこの印刷された情報（私が提供することによって得られるもの）を最大限に活用したいと思います。どうすればいいのか知りたいです。
私が考えたのは、次のような命令を出したことです。
dd bs=<some size> skip=<some size> count=1 if=/dev/sdc1 | od -Ax -tx1z -v
必要な詳細が表示されます。デフォルトでは、ファイルシステムからUSBハードウェアの詳細をインポートする必要があります。
このアイデアを提案していただいたり、同じアイデアを出す他のアイデアがあればお願いします。
答え1
ハードウェアの詳細はファイルシステムに統合されておらず、USBコントローラによって管理されているようです。
答え2
確認してくださいlsusb
デバイスが接続されると、dmesgも表示されます。
