stty：'标准输入'：设备的 ioctl 不适当（/dev/ttyUSB0 usb 2-1.1：cp210x 转换器）

我有一个 USB-WDE1 数据收集器连接到我的 Ubuntu 盒子。多年来一切都运行良好，直到我升级到 Ubuntu 16.04。从那时起，我得到了：

sudo stty < /dev/ttyUSB0 9600 -brkint -opost -onlcr -echo
stty: 'standard input': Inappropriate ioctl for device

dmesg显示：

命令ls给出如下结果：

$ ls -al /dev/ttyU*

我该如何解决这个问题？

提前致谢。

嗯，我有一个类似的问题：

...

我也不知道为什么这个 xpra 会冻结...
