Q:
QLC+ cannot detect my USB device
A:
QLC+ supports a wide variety of USB devices. First of all you should check if the
physical connection is OK. Usually a LED on your device should indicate if it is
powered up and working correctly.
If you are using Windows and your device is manufactured by Peperoni or Velleman,
please read the information on how to get them working directly on these help pages.
For licensing issues they both need an extra DLL file to work. Please check Peperoni
output plugin or Velleman output plugin
If you're using Linux, please check if your distribution detected the device when plugged
in. Basically the "dmesg" command should tell you something.
