Mac, Ruida Controller, doesn't recognize USB

  1. “Find My Laser” recognizes nothing.
  2. I’ve attempted to set up the laser manually many times. Talked directly to Thunder Laser rep who has the same laser and uses LB with his Mac via USB… Still, no connection.
  3. I use RDWorks regularly
  4. RDWorks is running on a Windows computer as RDWorks isn’t supported for Mac.

I’m happy to provide any information, and I’m grateful for any help.

What I meant is that LB shows no connection, but if I plug the USB in to my Mac with the laser powered off, the controller powers up, so that indicates the USB connection is there… Hopefully that clears up the confusion.
