qlcplus: uDMX: Unknown device

Dear qlcplus,

I’m testing the latest release qlcplus-4.10.5b (Gentoo Linux, compiled with QT5) with a USB-DMX512 cheap dongle and got the following error:

This plugin provides DMX output support for Anyma uDMX devices.
Unknown device
Cannot connect to USB device.

The relevant lsusb -v output is below:

I have checked the source code, 16c0:05dc is specified properly in uDMX plugin.

would you have an idea what’s wrong?

Thank you.

oh, wait a min. I did not see the horizontal scroll. Sorry my fault. There is a checkbox in the “output” column! Let me play around it before I close this bug.

Please let me know what else can be useful to debug my issue. Thank you.

To be honest I still don’t get your issue. If you see “Unknown device. Cannot connect to USB device.” it means a device is actually listed in the input/output manager. I saw it too and it might be a glitch in the device status (that I can easily fix), but it doesn’t mean the device will not work. Have you tried to activate the checkbox of the corresponding output line and see if it works ?
