    84 Some modems now support USB 3.0 for faster speeds.
     84Some modems now support USB 3.0 for faster speeds required for Cat6.

    8686Gateworks 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.
     
    8888USB 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]

    90 Typical USB 3.0 pins are:
     90USB 3.0 pins on the miniPCIe connector are:
    9191 * 23 - USB3.0_TX-
    9292 * 25 - USB3.0_TX+
     
    9494 * 33 - USB3.0_RX+
    9595
    96 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)
    97 
    98 {{{
     96Many of these devices support USB 2.0 as a fallback. To verify proper USB 3.0 link for a device look for that particular device with a 5000mbps speed as opposed to a 480mbps speed. For example:
     97{{{#!bash
    9998root@xenial-newport:~# lsusb -t
    10099/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 5000M
     
    113112        |__ Port 5: Dev 3, If 0, Class=Vendor Specific Class, Driver=, 480M
    114113}}}

     114  * Note above the 'qmi_wwan' device shows a 5000mbps link
