パソコンはWindows 7 Pro 32bitを使用しています。 シリアルポートが不具合を起こしたため、このケーブルを使用してシリアルポートを使うために注文しました。 USB 2.0ポートへいきなりケーブルを接続してみましたが、ドライバが当たりませんでした。 付属の小さなディスクを使ってドライバをインストールすると、その後は問題なくドライバが当たり、使用可能になりました。 USB3.0ポートは試していないので不明ですが、USB 2.0ポートを使うのが安心でしょう。 シリアルポートが不具合を起こした際には、こうしたUSB変換ケーブルは非常に重宝します。

Excelente calidad, se siente más robusto que otros y al mismo (o menor) precio, los acabados también se ven mejor. Funciona bien y se ve muy bien.

Quick Delivery, well packaged and good finish on product. Item recognized and drivers installed automatically on Windows 11 and Windows 10. Used for connection to CISCO Network equipment and worked without fault or concern Very Happy with this USB-RS232 cable. I would buy again if required.
