Hello List,

I did some experiments (changing cables etc) but always the same. But when tested with a windows system it worked all fine.
later i used a single port USB->Serial and all worked as expected.

I tested with: Opensuse 15.1 on a DELL latitude E5400

I would like to improve the situation, does anyone has that device ? any hints what to look at ?

please reply direct, i am not member of this list.
