Hello All, I am newby to this forum. I connect arduino leonardo to PC win7 x86_64, however it cannot be detected on device manager. The L LED and ON LED are continuously ON. I try different USB port and cable, it has same problem. I push the reset button but the two LEDs still on. Do I have to install specific driver before connect to PC?
I install the arduino environment but the problem still appear. I connect to my Macbook Air also and it did't have any notification of USB connected to the board.
