Subject: ttyACM strange chars appearing at connect
Date: Tue, 19 May 2020 12:14:55 +0000	[thread overview]
Message-ID: <52b8c126634058e3a455dc0ab8b0c542916db543.camel@infinera.com> (raw)

Whenever we connect a Linux laptop(4.19.118) to our ttyACM serial gadget we can see som strange
chars appearing in our gadget:
03�`3�03�x�x(in hex: 3033 efbf bd60 33ef bfbd 3033 efbf bd78 efbf bd78)
They appear witch c.a 1 sec in between.
I assume it is the laptops ACM driver emitting those, but why? Can these chars be turned off?
