> Could you possibly respond to the lights question and do you know anything about adjusting the current?
Unfortunately, the lights have never been a reliable indicator in cases like this. The current is factory pre-set (to a reasonable starting value), and should not be adjusted unless there is a specific reason to expect that it needs adjustment.
Not seeing the EBB in the device manager is very clear, as is the failure to contact it via RoboPaint RT or Inkscape. Please contact our shop directly via e-mail (reply to your order confirmation) or use the contact form ( http://shop.evilmadscientist.com/contact ) to request an EBB exchange. I’m very, very sorry for the hassle, and I’m glad that you were able to test with the other programs and with the other USB cable to pinpoint where the problem was.
