Hello, I have a problem with the NanoDMX adapter cable. The logfile says: ""DecoderMAD: can not initialize. Source file does not exist. virtual bool Na noDMX :: open (quint32, bool) "NanoDMX Interface" Initialization failed"". Does anyone have any idea why that is?

OK thank you

Did you build QLC+ yourself ?

What log file are you talking about ?

No, I have QLC+ installed with the Ubuntu Software Center.

And I have started QLC+ with this command:

Code: Select all

$ qlcplus -d 0 -g
That enable debug messages and store them in a log

I know your adapter is from DMX4ALL, in fact I change this thread title cause it was lacking the basic information.
It is similar to the Eurolite adapter because they both map to /dev/ttyACM, and believe me, I wrote the code to support it, so I know what I'm saying.

Now, more details please:
- do you see a /dev/ttyACMx device ?
- have you tried the "echo" command mentioned in the other thread ?
- what does dmesg say ?
- do you have processes trying to keep the device busy (e.g. modem manager as I mentioned in the other thread)

The more info, the more help.

Hi,

-Yes, I see a device (with

Code: Select all

watch 'dmesg | tail'
)

-dmesg says: [33852.960140] usb 7-1: new full-speed USB device number 11 using uhci_hcd
[33853.138324] usb 7-1: New USB device found, idVendor=03eb, idProduct=2018
[33853.138331] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[33853.138335] usb 7-1: Product: NanoDMX Interface
[33853.138338] usb 7-1: Manufacturer: DMX4ALL
[33853.141401] cdc_acm 7-1:1.0: ttyACM0: USB ACM device

-I see no other process that keep the device busy (and I can`t uninstall the ModemManager, but this is a system error and I don`t know, how to kill him :( )
