I am running Ubuntu 16.04 using brltty with a Varioulta 40 cell display.
I have 4 consoles open and of course the desktop (I prefer working at the
console to using terminals).
I see the following in my syslog which appears to be causing issues with
using a usb-to-serial converter among other things. Can anyone tell me
what is causing these messages and what the solution is?
