I've installed the latest version of Pattern Paint. The program opens and shows the example patterns. When I connect the LED strip (WS2812) and BT controller to the computer, the LED strip flashes every LED for a split second then goes dead. After reading through some other discussions, I looked to see if the computer was recognizing the controller - it is not. I followed the instructions on the trouble shooting page to reset the controller. Again, the LED strip flashed, then went dead. The computer gave a notice that it did not recognize the device plugged into the USB port. Pattern Paint still shows no controller.
I tried this on two computers, one running Windows 8 and one running Windows 10. Same problem on both computers.
Any thoughts? Thank you for your help
