fuse:
$(UISP) --wr_fuse_h=0xc9 --wr_fuse_l=0x9f

I was thinking that this was the cause the circuit wasn't working, every time i plug it i get "unknow device".

Will go back to double checking the circuit for hardware errors.

Any pointers on debugging circuit errors. should I look for specific voltages at the AVR pins?

I have
Vcc= 3,6V
D- (pin 2) = 3,2v
D+(pin 4) = 0;

Thanks

But...
Where can i find the correct ATMega8 Fuse bits (high and Low) for the standard HIDKeys circuit?

If some one could post the configuration bits would help a lot.
Im starting at Atmel AVRs, so the crystal fuse bits are very confusing.

Thanks in advance for any support.
