Hallo,

Ich habe ein Problem mit dem AVR-USB...

Wie muss ich denn die Fusebits setzen?

Als Takt benutze ich einen Quarz mit 16MHz und habe einen Atmega8 per
Z-Dioden an den USB-Anschluss gesetzt (genauso wie im Circuit-Beispiel).

Wenn ich jetzt die erstellte Hex-Datei in den Atmega lade (EEPROM-Datei
ist leer?!?) und ich das ganze an den USB-Port hänge kommt dass es ein
unbekanntes Gerät sei (Vendor und Produxt sind 0)...

Das hier ist meine USBCONFIG.h

und das hier ist meine Hauptroutine:
 #include #include #include #include #include #include #include #include #include #include "usbdrv.h" static uint8_t replyBuf[8]; void avrlab_init(void) { uint8_t i,j; j = 0; while(--j){ /* USB Reset by device only required on Watchdog Reset */ i = 0; while(--i); /* delay >10ms for USB reset */ } usbInit(); sei(); } uint8_t usbFunctionSetup(uint8_t data[8]) { uchar len = 0; usbMsgPtr = replyBuf; return len; } uint8_t usbFunctionRead( uint8_t *data, uint8_t len ) { return 0xff; } uint8_t usbFunctionWrite( uint8_t *data, uint8_t len ) { return 0xff; } int main() { DDRC = 0; avrlab_init(); for (int i = 0; i <= 7; i++) { replyBuf[i] = 0; } while (1) { replyBuf[1] = PORTC; usbPoll(); } return 1; } 

Ich hoffe ihr könnt mir helfen....
