I use an official STK500v2. You will find below, the result of a flash. 
This is really slow while writing (without any timeout msg). The reading
timeouts, and produce some missmatches. 

For the fuse, i'm not sure, fusecalc give me a different fuse than avrdude
found. 

In my initial email, I said the 32u2 is binary compatible with the usb162
but that's false. They have the same pinouts, the same registers but I don't
know the memory address. And worst, the 32u2 has 32k vs 16k on the 162 of
course. 

Thanks for help.
