     82== USB 3.0 Support ==
     83
     84Some modems now support USB 3.0 for faster speeds.
     85
     86Gateworks 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.
     87
     88USB 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]
     89
     90Typical USB 3.0 pins are:
     91 * 23 - USB3.0_TX-
     92 * 25 - USB3.0_TX+
     93 * 31 - USB3.0_RX-
     94 * 33 - USB3.0_RX+
     95
     96To 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)
