It works "out of the box", recognised as eth device. Same under Windows 10 in a VM of that Linux (devuan chimaera 64bit), BUT:

Under Linux it is extremely slow, mostly less than 50 kB/s, under Windows up to around 700 kB/s. Speed is limited to 7.2 Mbit/s by provider congstar. The stick is indicating LTE-connection.

Any idea how to get "full" speed?

Got me another stick (KuWfi) that works.
