TT-Connect CT2-4650 CI doesn't initialize (Timeout?)

I've tried to get a Techno Trend TT-connect CT2-4650 CI running under a Kali Linux, where I suppose the kernel is about the same as on a current Debian. The compilation ran just fine. The kernel module got loaded with no problems, but when I connect the device to my virtualbox I get the following messages in dmesg: [ 223.081774] usb 1-1: New USB device found, idVendor=0b48, idProduct=3012 [ 223.081780] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 223.081785] usb 1-1: Product: TechnoTrend USB2.0 [ 223.081789] usb 1-1: Manufacturer: CityCom GmbH [ 223.081792] usb 1-1: SerialNumber: 20130422 [ 223.335895] WARNING: You are using an experimental version of the media stack.

Any ideas are greatly appreciated.
