[Bug 2008920] [NEW] Brltty does not permit Arduino devices to run on ubuntu

[Alexandre Felipe Muller de Souza]

Public bug reported:

Every time I start a new ubuntu installation from zero I get some errors
on Arduino devices that does not recognize with the following error:

[  561.144042] usb 1-2: new full-speed USB device number 15 using xhci_hcd
[  561.293021] usb 1-2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.54
[  561.293028] usb 1-2: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[  561.293031] usb 1-2: Product: USB2.0-Ser!
[  561.294936] ch341 1-2:1.0: ch341-uart converter detected
[  561.295634] ch341-uart ttyUSB0: break control not supported, using simulated break
[  561.295695] usb 1-2: ch341-uart converter now attached to ttyUSB0
[  561.845448] input: BRLTTY 6.5 Linux Screen Driver Keyboard as /devices/virtual/input/input28
[  561.961485] usb 1-2: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1
[  561.961910] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[  561.961937] ch341 1-2:1.0: device disconnected


So I have to remove brltty manually (apt remove brltty), that just no problem. But I think this modulo shouldn't disable others serial devices by default. In summary its sad that, for default, ubuntu does not work with arduino. For me this is a bug, or brltty should be default if it can't live with others devices.
