 Please compare the modem pinout to the Gateworks pinout to ensure compatibility.

+== USB 3.0 Support ==
+
+Some modems now support USB 3.0 for faster speeds. 
+
+Gateworks routes USB 3.0 to select Mini-PCIe slots on the Newport GW62xx, GW63xx and GW64xx (the GW61xx only has USB 2.0). The Laguna and Ventana families do not support USB 3.0.
+
+USB 3.0 is typically routed through a Multiplexer shared with PCIe so proper configuration must happen at the bootloader layer described [wiki:newport/bootloader#hwconfig:miniPCIeSocketConfigurationhere]
+
+Typical USB 3.0 pins are:
+ * 23 - USB3.0_TX-
+ * 25 - USB3.0_TX+
+ * 31 - USB3.0_RX-
+ * 33 - USB3.0_RX+
+
+To verify proper USB 3.0 operation, look for a speed of 5000M in the usb device tree with the command shown in the example below (Bus 04.Port 1)
