Hi, I took the USB-CDC-example from the AT91SAM9260 software package from Atmel and it works fine, as it is.
But when I exchange the startup file by the one, delivered with µVision and change the project settings, to suit the modifications, the USB enumeration is not working any longer. The VBUS_ISR is not called and thus the device does not know, that it has been plugged in.
Does anyone have the same behavior? Any ideas how to solve it?
