Bug Description
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

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.
