I'm using an ATSAM4E16C microcontroller as a serial usb com port but it doesn't stay connected. After i plug it in i head the usb plugged in sound, and then it enters a loop where every 5 seconds or so it disconnects and reconnects immediatly.
I used this microcontroller on my own board and i was thinking if it could be because of a bad crystal oscillator. In the datasheed of the uC it said to use a crystal with a Load Capacitance between 12 and 18 but i used one with 10pF, and 15pF capacitors on each end. Could this be the issue, or should i look somewhere else?
