I’ve used the Arduino IDE with a genuine Arduino Uno board for experiments for a few months without trouble. Recently, I wanted to permanently put an Uno in a desktop project, so I purchased some budget Arduino Uno compatible boards. The budget boards seem fine, but the Arduino IDE doesn’t recognize any of them. When connected, the boards show up as an “Unknown Device.” I am using Windows 7 32-bit. Does anyone have any pointers on how to make this board work?
