USBDemo, something to learn USB a little bit

[mister_e]

i would guess...

asm
    __CONFIG    _CONFIG1L, _PLLDIV_12_1L  & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
                            ;              ;                      ; USB clock source comes from the 96 MHz PLL divided by 2
                            ;              ; [OSC1/OSC2 Src: /1][96 MHz PLL Src: /2]
                            ; Divide by 12 (48 MHz oscillator input)


    __CONFIG    _CONFIG1H, _FOSC_ECPLLIO_EC_1H & _FCMEN_OFF_1H & _IESO_OFF_1H 
                            ;                  ;               ; Oscillator Switchover mode disabled
                            ;                  ; Fail-Safe Clock Monitor disabled
                            ; External clock, PLL enabled, port function on RA6, EC used by USB
                            
    ;
    ;   other __Config
    ;
endasm

Look table 2-3 in the data sheet. there's few other setting available. Not sure the divide by 12 is the best option when you can feed it directly.
