the cable is connected to a host PC. It is not shown when connecting after the
system has booted. Unfortunately, I cannot generate the error reproducible, e.g.
I just tried 10 times and nothing was shown. Maybe just forget it for now if
no one has an obvious idea. I'll try to find some reproducable situation and will
report back.
Thanks
