Sierra Wireless (Dell Wireless 5570 HSPA+ (42Mbps) Mobile Broadband Card)

I'm pretty sure the fcc thing is possible with qmi embedded in mbim. See my recent experments with the usb comp commands. 

Testing it is pretty straight forward, since you only append your prepared qmi messages to mbim. Or seeing it the other way:prepend an mbim header to qmi messages.

It would be interesting to know whether this is the method used by windows, or if there is some more direct mbim service/cid for this. So if anyone can snoop..
