我想告诉大家ModemManager别管我的 Tungsten E (Palm Pilot)。我正在运行 Ubuntu 16.04.6 LTS
我的日志告诉我：

我想阻止ModemManager尝试任何事情，/dev/ttyUSB[01]甚至/dev/ttyUSB*。

创建 udev 规则文件，例如/etc/udev/rules.d/80-palm.rules：
ATTRS{idVendor}=="0830", ATTRS{idProduct}=="0060", ENV{ID_MM_DEVICE_IGNORE}="1"
重新加载 udev 规则：
udevadm control --reload-rules && udevadm trigger
插入您的 Palm 设备。
