EDIT: Problem is solved now. I just followed Helders steps how to solve it. http://www.sudomod.com/forum/viewtopic.php?t=1185
I also twisted the D+ and the D- wires and detwist the other ones

Hi guys,
right now I am in the final stage of my GBZ-Project. Everything is working fine, except my USB-Port for transferring the ROMs and config-files. And I may need your help. As you can see in the images below the port is (hopefully) wired as it should be. If I plug in my USB-stick its light is blinking for a short period of time. After 5 to 10 seconds the light stops it and starts glowing until it is plugged out. After that I restart my raspberry but there were not ROMs transferred. I have already checked the USB-stick with my raspberry before I start wiring it all up and back then it worked as it should. Inside the spoiler you will find how I wired the USB-port.

I know wires can influence each other because they “producing” electromagnetic fields (It is hard to explain for me since English isn’t my native language). Do you have any suggestions how I can prevent the USB-data from being influenced? Any help will be appreciated. :)

Greetings,
Phil

Go to my support thread in my signature, the first post has info on how to setup the usb for certain devices in the config.txt.

You also need to twist the D+ and D- wires with each other not with 5v as you have done.
