在/dev/ttyUSB中没有显示STM3210 USB到串行适配器

Question

我在易趣上找到了一把乙烯基切割机，然后买了下来。

然后我偶然发现了这个视频：https://www.youtube.com/watch?v=3tZXsUGEJ-E，它证明了在linux上使用这种设备是可能的。我已经安装了墨迹，但无法完全弄清楚如何连接到设备。

lsusb -v为设备提供了以下内容：

dmesg给出了这样的输出：

..。当我插入设备的时候。(这是执行sudo dmesg -C后的一个干净捕获)

我在网上读过很多不同的文章，有些提到了udev规则等，但无论如何，ls -l /dev/ttyUSB*返回ls: cannot access '/dev/ttyUSB*': No such file or directory

我遗漏了什么？

Answer 1

结果发现问题不是我想的那样。

我发现打印机是作为usblp2设备(usblp2)出现在/dev/usb/lp2上的。这意味着我必须选择并行端口。这并不是直接出现在墨迹中，而是需要重新启动。
