This forum is great! After been trying to get the serial port working for three days, I sent the post here and in 5 minutes I came up with the solution. It was a access right problem. I just changed the rights for /dev/ttyACM0 by using sudo chmod 777 /dev/ttyACM0 and it started working straight away!
Now I have been trying to get my raspberry connected to my thermiq, without success. I have tried to blacklist the acm and I have tried to soft link ttyACM0 to ttyUSB0. in taloLogger it works just fine but I cant get it to work with thermiq. Any other ways I should try? Could anyone explain why it isn’t possible to just change to ttyACM0 in the Thermiq_Linux.ini?
