RFID阅读器ubuntu 20.04

Question

我拿到了一个RFID读写器。它作为一个简单的键盘输入。因此，如果我打开文本编辑器并扫描一些RFID，它就会将代码打印为text =)

我安装了RFDump，在找到它的串口时遇到了问题。我有个小剧本印着这个

/dev/video1 - Chicony_Electronics_Co._Ltd._HD_WebCam
/dev/video0 - Chicony_Electronics_Co._Ltd._HD_WebCam
/dev/input/event7 - Chicony_Electronics_Co._Ltd._HD_WebCam
/dev/input/event17 - Sycreader_RFID_Technology_Co.__Ltd_SYC_ID_IC_USB_Reader_08FF20140315
/dev/input/event6 - Logitech_USB_Receiver
/dev/input/mouse1 - Logitech_USB_Receiver

国际劳工局：

Bus 001 Device 009: ID 08ff:0009 AuthenTec, Inc. SYC ID&IC USB Reader

-v选项没有显示任何额外的路径

如果在RFDump串口中复制该路径(/dev/ port /event17 17)，它会说：

Could not initialize RFID reader.

希望这是有意义的。如果有些人能分享一些智慧的话，让它发挥作用，那么就友好点。

@Sebastian I运行dmesg| grep 'SYC ID&IC USB Reader'并输出：

当我和苏多一起做的时候，原来的问题就说了。当我和苏多在一起的时候，我突然出现了：

Serial port not set. Please set the serial port in the preferences or use the -p argument and restart rfdump.

另外，我在串行端口字段中有一个选项：/dev/ttyUSB0

当出口sudo运行时，我得到了终端信息：

could not load preferences /root/.config/rfdump.ini : No such file or directory
using /usr/share/rfdump/rfdump.glade

所以我在很多方面都很困惑
