Choosing correct communication cable

My Chinese 100watt laser with ruida controller has 2 USB ports and 1 Ethernet,
I want to run the laser with light burn software so my laptop has USB out female the laser has USB female port. Having difficulty finding a male to male USB .
I was warned by a computer tech that installing incorrect cable could fry one of the devices???something like a USB cable specifically for two computers to communicate???

Pictured, see the correct port on the controller to communicate with the PC. The USB cable type you are seeking is referred to as USB A to USB B Cable - M/M

My laser doesn’t have that usb b. It has 2 USB A. And 1 Ethernet port

My apologies. I had Ruida on my mind. I see you have a Shapeoko xxl. I am not familiar with that controller on that machine (but i bet someone else is).

@Spud59, share a few images of what you have, and we may be able to better offer assistance. :slight_smile:

I found the proper male usb to usb was hidden in packages that came with laser . Thanks for the assistance
