Port failed to open

Hi all.
Last couple of days when I’m using Lightburn it won’t recognize my device.
It is saying Port failed to open.
Unplugging USB connection and powering off device won’t help.
And when trying to Add New Device it wont find it.
It will find it after couple of times plugging in and out USB connection.
But I need Add New Device every time, it won’t recognize old ones.
Laser is Neje 2s plus
Any advice what is causing this behavior please?

Have you tried changing the USB cable?

Hi Jim.
No I didn’t.
My USB connection is going through USB splitter. Camera and Laser are connected there.
You think that is the reason?

Maybe you can try

I will try. Thanks
