FTDI(Future Technology Devices International)是一家提供 USB 转串行接口芯片和模块的公司,其产品广泛应用于各种电子设备中进行串口通信。Linux 中的 FTDI SIO 驱动是一种用于支持 FTDI 芯片的驱动程序,它允许 Linux 系统通过 USB 接口与使用 FTDI 芯片的设备进行通信。
对于之前ftdi官方推荐的rmmod ftdi_sio, 我只能说这种做法十分的暴力, 其实使用unbind就足够了. 通过lsusb -t找到设备对应的节点, 然后执行echo ${dev_path} > /sys/bus/usb/drivers/ftdi_sio/unbind. 对应usb设备可以在/sys/bus/usb/devices目录下找到. $ lsusb -t # snip ... /: Bus 03.Port 1: De...

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: ...
