I'm working on a project using an ATXMEGA64A4U, powered by the USB port.
I'm trying to have it recognized by the HOST but nothing on the bus.
I have checked the D+/D- signals, and according to the selected speed they have the correct values, so pull-ups ok.
I have checked the bus lines using a USB analyzer from Lecroy, and nothing detected, no activity at all.
I'm entering inside the USB_BUSEVENT_vect ISR once, with the status set to 0x60, and nothing else after.
Can someone explain me why?
I have added my main.c file, I think this is enough for the code.
