You just showed output which showed that it was connecting to ttyUSB1…
What we are trying to do is see if the Ruida device is getting created so when you look at dmesg output and it shows the device then that is what you are wanting to look for. it showed ttyUSB1 so that is the device in the /dev directory you should have looked for.
The reason why we’ve been messing with the brltty application is because others( Please read the forum post I linked above ) found that the brltty application is attaching to the ttyUSB0 device and for whatever reason removing it.
also, for the 3rd time will you please run the 4 steps, I’ll list them again but this time, unplug your Ruida cable and turn it off, shutdown your computer, restart both the Ruida and the computer, log in, then
sudo modprobe ftdi_sio
echo 0403 6001 | sudo tee /sys/bus/usb-serial/drivers/ftdi_sio/new_id
- Plug in the device
look to see if the device has been created.
