Thanks for your hint with the short guide, but it simply says "install ArakAttack and use it". But, this does not work for me here, I just tried it again. I simply get system freezes, and sometimes, if I am lucky, it works for a few seconds and Poseidon gives _a lot_ error messages sayin "Houston, we have a problem! P2V undetected!". But I never get USB2 speed.
