Lesenswert?

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

General Description:
16
This file is an example configuration (with inline documentation) for the USB
17
driver. It configures AVR-USB for USB D+ connected to Port D bit 2 (which is
18
also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
19
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
20
other hardware interrupt, as long as it is the highest level interrupt, see
21
section at the end of this file).
22
+ To create your own usbconfig.h file, copy this file to your project's
23
+ firmware source directory) and rename it to "usbconfig.h".
24
+ Then edit it accordingly.
