Flickers likely based on usb-dmx

I have recently started to use qlc+ and when I try to use my laptop my lights randomly flicker. I have had no issues of the sort when using the ETC colour scource 40av but when I use qlc+ they constantly flicker.
I am wondering if my super cheap usb to x converter may be to blame?
Any advice or tips would be greatly appreciated.

Massimo,
May I add that GrandMa f.i. has a fixed 30Hz refresh rate? So they choose to be on the safe side of the norm.

Yep, I'm aware of that...that's why Open DMX is already @30Hz in the code

PRO adapters though could work at 44Hz steady.
