AVR-Chat

Hi,

just in case someone finds this thread later, here's the solution. AVR
Studio 4.13 SP2 messed up the fuses and couldn't fix them either. I
installed 4.14 beta and was able to repair the fuses and get my code
loaded again with the old JTAG box.

My butterfly (tried only 1 so far) works fine again and the project
can proceed. I also ordered an AT90USBKey, atmega16 (for gnusb) and an
AT90USB16. So I have some options now.
