Linux Mintで奇妙なUSB問題が発生しました。一部のUSBデバイスは引き続きリセットされます。奇妙なことは、カーネルがリセットしようとしているデバイスでさえランダムであるということです。または私が離すと、別の場所に接続されます。
しかも、マウスを再接続してからかなり時間が経って(残念ながら初めて接続が覚えていません...)
私はこれがハードウェアに関連していると思います。 Windowsでは同じ問題が見つからず、オシロスコープをマウスコードに接続しましたが、不規則性が見つかりませんでした。
デバイスはランダムで、時間はランダムで、時には数時間動作し、時にはマウスを10回連続してリセットします（これはいくら言っても残念です）。
これが自動サスペンドによって発生する可能性があることをどこかで読みましたが、これを無効にしました。リセットは依然として発生します。
新しいバージョン：20
カーネル: 5.4.0-54-一般
私にとって非常に奇妙なことは、それがどれほどランダムであるかです。ログを見ると、最初はヘッドセットをリセットし続けていきますが、突然マウスに切り替わりますが...少なくともしばらくの間。

はい、ヘッドフォンが外れていても問題が発生する可能性があります。
