Hi there!

I just ran into the same issue (Linux Mint 20.1). My FTDI USB-DMX inteface is recognized by QLC 4 without problems, but QLC 5 hasn't shown it.

I found the following message while starting QLC:

Code: Select all

void IOPluginCache::load(const QDir&) "libdmxusb.so" doesn't contain an I/O plugin: "Cannot load library /tmp/.mount_QLC+_5I7AMcH/lib/qt5/plugins/qlcplus/libdmxusb.so: (libftdi1.so.2: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden)"

After installing the package libftdi1-2 (libftdi1 was already installed, probably with the installation of QLC 4 as a DEB package), the message disappeared.

Maybe this would be notable in the future documentation QLC 5.
