The gadget is the evaluation board with the module together.

Is it correctly powered and initialized? Yes. The evaluation board was first delivered with WindowsCE. With this, the USB connection worked fine. But with the Linux kernel, it just doesn't want to work. I also read http://www.linux-usb.org/gadget, but the information did not help. Thank you anyway for thinking about it with me together.
