Reply to Midi Fighter Spectra is not recognized

Hi Folks,

got my Spectra today and plugged it in my laptop. Nothing happened except the bottom right arcade button is lighting.

- Neither any USB installation popped up nor any device showed up in the device manager.
- The Midi Fighter Utility also does not recognize any device.
- I tried all three USB ports of my laptop.
- Wanted to listen midi-signals with the midi-ox tool, but it can't see any device too.

I guess it makes no sense with bootloader menu or anything like this?

Please help me I finally want to start making music with my Spectra!!!!

Laptop:
Lenovo T400, Windows 7 64bit, Should have enought power

PS: Pushing the bottom right button is bringing the next button to light up. Extra feature?

EDIT:
So i thought that maybe the firmware was not ok or something like that.
I was able to get in the bootloader mode. I wanted to connect to the device with Flip by Atmel. In the device manager the usb device is named "ATMEGA32U4". Is that correct? Some instructions in this community say that is has to be named "AT90USB162". The section of the device is the same as in the instruction to flash the mf. When I select the "AT90USB162" in Flip I can't connect to the device. Error message when i want to "open": "Cannot open the USB device".

I appreciate any help!!! Thanks!
