The box is not repsonding at all, so also a firmware update seems
not working but yes I will setup a windows this week because
I have no windows and after that I will remove it as fast as possible :-)

The second thing is that the jtag box work fine under linux, but
I must change some things in avarice for that. There is one
misterious thing for the programm counter in avarice where
porg counter is calculated with pc/2+1 I think correct
is pc/2. With this patch all seams to be ok. I reported this
"bug?" years ago without any resonance. Maybe others have not this problem.
The bahviour with the program counter is also wrong for original jtag
box from atmel so the patch is needed for both, olimex and atmel box.
