我的 IOGEAR SD 卡读写器在 Ubuntu 上被识别（通过使用 VM ware），但是当我尝试连接到“可移动设备 -> Alcor Micro Flash 卡读写器”时，出现以下消息：
The connection for the USB device "Alcor Micro Flash Card Reader/Writer" was unsuccessful.
The device is currently in use.
但我认为它没用过。我应该为这个使用 IOGEAR 驱动程序吗？当我连接读卡器时，Ubuntu 自动识别了“Alcor Micro Flash Card Reader/Writer”。
我该如何解决这个问题？
