Hi Arduino Community,
I bought an Arduino Uno rev3 clone from china several months ago. Link to the Product: http://www.fasttech.com/products/1008/10000015/1001700-arduino-uno-r3-rev3-development-board
I was able to upload the blink sctech with no probems. Everything worked fine. After a few months I had some spare time to experiment with the arduino. But I it was not possible to conncect the board with the pc. Neither Windows 8.1 (64bit) nor Ubuntu 14.04 (64bit) were capable to regcognize the board. The ON-LED shines green and a orange led blinks while board is plugged in with USB and PC.
I allready tried it with diffrent USB cables and on two other PCs (Win 8.1 64bit / Win 7 64bit) with no success.
Please help me. Thanks in Advance!
