Static mapping of USB-devices

[deme]

Hey Armin,

this is what we do on a stock rasbian:

1) figure out the serial number of the attached device:

Code:

$ udevadm info --name=/dev/ttyUSB1 --attribute-walk

2) create a rule for static mapping in /etc/udev/rules.d/10-usb-serial.rules

Code:

SUBSYSTEM=="tty", ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678", ATTRS{serial}=="xxxxxxxxxx",  SYMLINK+="ttyUSB_MyDevice1"

3) load the new rule (only required before reboot)

Code:

sudo udevadm trigger

4) verify

Code:

$ ls -l /dev/ttyUSB_MyDevice1

now, you can adress the device as ttyUSB_MyDevice1 instead of ttyUSB0 or whatever it might be mapped to.
