First of all, thanks for the tips!
I didn't really find the problem, it wasnt the solder connection, capacitor or data line resistor, however:
When I plug the arduino in with my mini USB cable it everything works just fine, but with the direct USB wire I soldered on RAW Pin, Ground PIN and USB Data wires directly to the ATmega it doenst work like I showed.
I still dont know what caused my problem but, I just use it with the mini USB now.
Thanks!
