Two FTDI USB Dongle
Posted: Fri Jan 10, 2020 3:11 pm
Hi,
I have QLC+ 4.12.2 (from AUR) installed on a laptop with Manjaro Linux and two USB-DMX adapters with the FTDI FT232 chip (which don't seem to have a serial number, if I showed you a picture of them you couldn't distinguish them either...).
The problem is that I can make only one put out DMX signals the other one appears to never get patched to a univers.
Here is what I have tryed and observed:
I hope you can help me with this issue. If you need additional information (lsusb output etc.), tell me. I hope I can provide it. Thanks in advance.

Here is what I have tryed and observed:
- enabling or disabling the hotplug feature
- Connecting the dongels one after the other or both at once
- blacklisting the FTDI dirver
- after supposedly patching the second (in chronological sense) to a univers, it still say I should patch it to one to find out how well the timing is
- if the FTDI diriver isn't blacklisted, only one TTYUSB device from /dev/ vanishes
- The Problem does not seem to occur on Windows Vista
I hope you can help me with this issue. If you need additional information (lsusb output etc.), tell me. I hope I can provide it. Thanks in advance.
