I have a MacBook air with no OS on it and I want to install windows 7. The problem is that no device is being recognized on the usb port. I have tried different usb sticks with different OS and different usb dvd drives with different OS (Linux, Windows, OSx)
Curious is that the USB Port did work as there was OSx installed.
So what can I do to get devices to be recognized on the usb port?
