DMX Interface DW-Lighthing not found on Raspberry

[jocz]

Hi there,

I use a simple USB DMX Interface from dw-lighting.de with QLC+ on Windows.
Now I want to start with a raspberry pi - but on the pi the USB interface is not found...

Do I have to install a special driver or something else?

otherwise what usb interfaces will work on the raspberry?

Thanks,
Jochen

On the RPi there's Linux running.
Can you provide the last lines of the 'dmesg' command showing the adapter USB VID/PID ?

I found this in the dmseg result:

[ 2.193201] usb 1-1.5: New USB device found, idVendor=0403, idProduct=6015
[ 2.193215] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 2.193239] usb 1-1.5: SerialNumber: 11111110000

Thanks for the info.
It's indeed a FTDI chipset, but the PID 6015 is not recognized by QLC+ (only 6001 is)
I might add 6015 to the code, but we need to understand which protocol this device supports (enttec open ? enttec pro ? dmx4all ?)

Which protocol do you use on Windows to make it work ?

as per linux info provided Open DMX
Quoting the site:

To use the driver is a bit tricky because the FTDI Driver has the same USB-ID and so Linux loads that driver as soon as the DMX USB dongle is connected. The easiest way to prevent this is by removing the FTDI module out of the /lib/modules/ directory to place where the kernel can’t find it. Another solution would be to recompile the kernel without FTDI support.

After the dmx_usb module is loaded the dmx_usb_test program can be started to test if things work. If things don’t work, I wish you happy kernel hacking

Hi,

i've been off for work for a few days - but today i checked the Windows Configuration (it's German, but i hope it's OK) of my dmx interface

Alright, so it works with the basic Open DMX protocol.
When I have some time, I will add PID 6015 and provide a cross compiled version of the DMX USB plugin for the RPi.
Please be patient.
