Greetings. I'm using a Lixada USB uDMX 512 cable to connect my lights to my laptop. Strangely when using QLC+ on kUbuntu (KDE version of Ubuntu) the cable I guess somewhat restarts and the light becomes red. That always happens 40-60 seconds after the start of QLC+, I can confirm that the cable is working perfectly, because when using QLC+ on a Windows machine this bug doesn't happen. The cable successfully connects and stays connected until I close QLC+. (Tested it and works for 5 hours). Any ideas?

Greetings, I started digging and what I have so far:

I changed the frequency to 16hz, still the same issue.

Rules are being applied.

In KSystemLog I get:
usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd UDMXDevice rqt 64 rq 2 len 512 ret -71
usb usb1-port1: disabled by hub (EMI?), re-enabling...

Do you have any ideas?

That's an issue with laptop USB ports, to resolve it I bought a powered USB hub.
