解决方法:检查内核日志(dmesg),确认驱动是否加载成功。如果驱动未加载,可以尝试手动加载驱动(modprobe ftdi_sio)。如果设备 ID 不匹配,可能需要更新或修改驱动代码。 权限问题 原因:普通用户可能没有权限访问串口设备。 解决方法:将用户添加到dialout组,或者修改设备文件权限(不推荐)。
需要着重说明, 最后一点是过往使用中的另一个痛点: 其实使用ftdi芯片的设备不在少数. 在我的工作环境中还有另外两种设备会使用到ftdi的芯片: 一个是xilinx artix 7 FPGA, 另一个是一条做工优秀和外面那些地摊货不一样的蓝色串口线. 每次需要同时使用ftdi232和其中一个设备时,rmmod ftdi_sio这条命令就十分的令人...

though I'll start doing that shortly. I'm finding that the input side of the ftdi_sio driver seems to get stuck after some seemingly random amount of data has been read. I'm putting the device in raw mode with just about everything disabled, and verifying that with stty: ...
