I have the same problem, impossible to make the card being recognize by the computer, the drivers are inefficient. I even downgraded to Windows 7 to try but there is no way to make it recognized.
However, if I put the LinkIt Assist firmware on the LinkIt One card I can manage to build and push a program into the card (LinkIt One). But I have yet to find a way to push program on the LinkIt Assist.
Is anybody having the same problem ?
