Update as of 19.02.2013 due to demand which driver works:
The driver is available directly in the forum under [...]. Since just read a bit, which fit. I have read the "Windows Driver November 2, 2011" from the thread.
The only problem is that Windows does not find these automatically, you have to specify the driver directly in the installation dialog of Windows. And then select the correct card (in my case the stick is displayed as "USB 2875", so I have chosen this variant in the selection dialog box by selecting the driver and the warnings from Windows ignored).
