Ubuntu串列埠
1，檢視USB0的繫結資訊
cmd->
udevadm info /dev/ttyUSB0 
out->
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，替換指令碼中的欄位：
SUBSYSTEM=="tty", ENV{ID_PATH}=="pci-0000:00:14.0-usb-0:2:1.0",MODE="0666", SYMLINK+="自己取得名字"
3，新建檔案，名字為：98-com-udev.rules，增加上述欄位
copy到如下路徑中 /etc/udev/rules.d/
