Old Enttec DMX USB Pro

[teletobi]

Hi,

I have an old Enttec DMX USB Pro from about 2006. I can't get it to work with qlc+ on my RasPi. It shows up in the Inputs/Outputs sometimes, but when I chose it and try to send a Signal it doesn't react.

Anyone a Idea what could help?
I Just need some Basic DMX Functions like Dimming and sometimes Flashing.

Thank You,
Tobi
