+
+description:
+  The Infineon/Intel XMM6260 is a 3G-focused, slim modem platform designed
+  for smartphones, data cards, and Machine-to-Machine (M2M) applications.
+  The modem is usually connected via the application processor's USB line
+  in HSIC mode; however, to work properly, the modem must control this line.
