You're loading CDMA2000/EVDO firmware on your card, not UMTS/HSPA
firmware.  Chances are, since you're in Germany, you want the UMTS
firmware.

Unfortunately, you have to figure out from the Windows drivers what
firmware files are for what technology.  There's a text file that
describes what the firmware directory numbers mean, and what provider
they are for thats stored somewhere under the Gobi downloader directory,
which is often stuffed directly onto C:\.
