【Ubuntu】绑定串口号

1，查看USB1的绑定信息

udevadm info /dev/ttyUSB1

P: /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0/ttyUSB1/tty/ttyUSB1
 
N: ttyUSB1
 
S: serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0
 
S: serial/by-path/pci-0000:00:14.0-usb-0:2:1.0-port0
 
E: DEVLINKS=/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0 /dev/serial/by-path/pci-0000:00:14.0-usb-0:2:1.0-port0
 
E: DEVNAME=/dev/ttyUSB1
 
E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0/ttyUSB1/tty/ttyUSB1
 
E: ID_BUS=usb
 
E: ID_MM_CANDIDATE=1
 
E: ID_MODEL=USB-Serial_Controller
 
E: ID_MODEL_ENC=USB-Serial\x20Controller
 
E: ID_MODEL_FROM_DATABASE=PL2303 Serial Port
 
E: ID_MODEL_ID=2303
 
E: ID_PATH=pci-0000:00:14.0-usb-0:2:1.0
 
E: ID_PATH_TAG=pci-0000_00_14_0-usb-0_2_1_0
 
E: ID_REVISION=0300
 
E: ID_SERIAL=Prolific_Technology_Inc._USB-Serial_Controller
 
E: ID_TYPE=generic
 
E: ID_USB_DRIVER=pl2303
 
E: ID_USB_INTERFACES=:ff0000:
 
E: ID_USB_INTERFACE_NUM=00
 
E: ID_VENDOR=Prolific_Technology_Inc.
 
E: ID_VENDOR_ENC=Prolific\x20Technology\x20Inc.
 
E: ID_VENDOR_FROM_DATABASE=Prolific Technology, Inc.
 
E: ID_VENDOR_ID=067b
 
E: MAJOR=188
 
E: MINOR=1
 
E: SUBSYSTEM=tty
 
E: USEC_INITIALIZED=78133

 

2，新建文件，名字为：my-usb-udev.rules

sudo gedit /etc/udev/rules.d/my-usb-udev.rules

3，增加字段

SUBSYSTEM=="tty", ENV{ID_PATH}=="pci-0000:00:14.0-usb-0:2:1.0",MODE="0666", SYMLINK+="USB-1"

4，打开串口从 /dev/ttyUSB1 变成了 /dev/USB-1
