当我将读卡器插入 USB 端口时,系统无法识别它,并且其中的红色 LED 持续发光(与正常运行时 LED 只发光并闪烁一段时间然后消失的情况相反)离开)。
我不知道如何让阅读器在 Linux (OpenSuse) 中运行。当我lsusb
在命令行中运行时,我看到插入上述设备后有一个新条目
总线 003 设备 002:ID 067b:2303 Prolific Technology, Inc. PL2303 串行端口
dmesg
插入设备后输出的新条目为

如何检查“加载模式是否与 USB 信息匹配”?
如果我只有 Windows 版的驱动程序,如何才能获得适合 Linux 版的驱动程序?
无法从其他应用程序使用该设备的其他原因可能是什么?
