Wireless M-Bus / Techem heat cost allocators

Hello to all,

is anyone using the above mentioned binding, see also the following link?

I got the problem, that when i use this binding, my symlinks are not working. See here: click me.

When ever i use this binding including the usb stick needed, my symlinks are not working, as well as that i cannot choose another serial port than the one needed for this binding, all the other serial ports are not listed anymore inside paper ui. see here, the marked circle. grafik

any idea?
