What was my problem
I had a big problem with my esp8266. I couldn't upload anything to it using the Arduino IDE 2.2.1, the ttyUSB port couldn't be found.
When I plug my esp8266 into the USB Port, it shows up in the port selection in the Arduino IDE but then disappears imminently.
dmesg | grep ch34
[ 7.286317] usbcore: registered new interface driver ch341
[ 7.286328] usbserial: USB Serial support registered for ch341-uart
[ 7.286342] ch341 1-3:1.0: ch341-uart converter detected
[ 7.304530] usb 1-3: ch341-uart converter now attached to ttyUSB0
[ 7.804730] usb 1-3: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1
[ 7.811803] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[ 7.811814] ch341 1-3:1.0: device disconnected
As shown above, the esp8266 is connecting, but then disconnects.
