  1. Find out /dev/ttyWHAT

  2. sudo udevadm info --name=/dev/ttyWHAT--attribute-walk

  3. edit /etc/udev/rules.d/90-usb-dagor.rules (sudo vi ...)

  4. add a line like this:

    SUBSYSTEM=="tty", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0042", ATTRS{serial}=="853323433323516040B0", SYMLINK+="dagor_dome"

  5. reset USB subsystem: sudo udevadm trigger

However...

Cheapo USB chips don't have serial numbers o_O. And of course, have all other attributes the same. so we are only left with physical ports as the distinguishing element.

In that case:

KERNEL=="ttyUSB*", KERNELS=="2-1.3:1.0", NAME="dagor_fans"
