[SOLVED] Linux - Eurolite USB DMX512 PRO

Post by nemo » Mon Mar 07, 2016 6:34 pm

Hello,
Recently I bought Eurolite USB DMX512 PRO, first I tried to connect device with win 10 OS, then I discovered that it only runs with linux. So I tried with Ubuntu 14.04 64-bit device shows in Input/Output panel but when I select it I get this error:
"An error occurred while trying to open the selected device line.
This can be caused either by a wrong system configuration or an unsupported input/output mode.
Please refer to the plugins documentation to troubleshoot this.".

Thanks for your help.

Hi, make sure your user have the rights to write on the device.
Typically it should be /dev/ttyACM0

you can try this from a terminal:

Code: Select all

echo "foo" > /dev/ttyACM0
and see what happens.

Most likely you need to add your user to the 'dialout' group or kill the ModemManager which is an annoying service of Ubuntu blocking every "modem related" device
