Running Ubuntu 16:04. I have bought a serial device(ttl) to USB called cp210x.
It works most of the time, but after a while it can suddenly disconnect.
There are two ways to activate it again, one is to restart ubuntu, the other is to try a different USB-port. The latter only works sometimes.
Running the following command
dmesg | egrep --color 'serial|'
Outputs something like:
