FTDI USBハブは接続を切断/再接続し続けます。

FTDI FT4232Hを連続的にドロップして再ロードできるシステムがあります。ケーブルを交換してみましたが、まだこの現象が発生します。

usbcore.autosuspend=-1自動中断の問題かもしれないと思ってカーネルブートパラメータで設定しようとしましたが、それでも発生します。

私は長い間、さまざまな種類のマイクロコントローラ開発ボードを使用してきましたが、USB 3ポートまたは外部USBハブを介してUSBシリアルアダプタを接続すると、この問題が発生する可能性があることがわかりました。私はいつもUSB 2を使って最大の成功を収めました。不要なポート外部USBハブ。
