... To use the USB interface of the AT90USB, the clock source should always be a crystal or external clock oscillator (the internal 8MHz RC oscillator can not be used to operate with the USB interface). Only the following crystal frequency allows proper USB operations: 2MHz, 4MHz, 6MHz, 8MHz, 12MHz, 16MHz. The AT90USBKey comes with a default 8MHz crystal oscillator. VCC ...
