There is also a /dev/serial/by-id but there will only be one entry there for this device because it shows the last one connected. FTDI chips will each have unique entries here.
Cheap chips won't, but they each have an entry under /dev/serial/by-path. This position, and the device names, should persist across reboots. If you have a lot of changes to your USB devices, plug all the CH340 devices into the same hub, then plug that in. The devices will enumerate in the order that they are plugged in to the hub.
This one-hub trick should work for MacOS and windows too, they should come up in the same order.įor devices with a unique ID such as FTDI you can set a udev rule that sees it's serial number and then creates a symlink to that device, it's straightforward.įor devices with the same or no Serial number, it's a lot more complex. When the device matches the product and vendor of the cheap arduino, it runs the script 'cheapduino.py' with the device as argument, for instance I created a udev rule that looks like this: ARDUINO CH341 SERIAL DRIVER LINUX 3.16.0 SERIAL NUMBER
The script then creates a symlink /dev/THX1138 that points to /dev/ttyUSB0 Then the cheapduino script connects by serial to the device and sends the string 'ID' and the software on the device responds DEVID=THX1138 or whatever. There are a lot of drawbacks to this method. The script must time out if the software on the cheapduino doesn't answer. ARDUINO CH341 SERIAL DRIVER LINUX 3.16.0 SOFTWARE Also this is not using the SYMLINK function of udev so it won't clean up dead links on disconnect, but it will overwrite them on reconnect. All of your cheapduinos must have this functionality in their software, with different device IDs set. They all must use the same baud rate as the script unless you want to write a very complex script that takes a long time.
