 Examples:
+ * Newport GW640x: steer the front panel USB2 signals to the J10 miniPCIe socket which uses CN80XX GPIO_20 which is Linux gpio-484:
+{{{#!bash
+# export and configure the GPIO as an output high
+GPIO=484
+echo $GPIO > /sys/class/gpio/export
+echo out > /sys/class/gpio/gpio$GPIO/direction
+echo 1 > /sys/class/gpio/gpio$GPIO/value # 0=front-panel 1=miniPCIe-J10
+}}}
+  - Note that on Newport you can steer this at boot time using the {{{hwconfig}}} bootloader env variable (see wiki:newport/bootloader#hwconfig)
  * Ventana GW52xx: steer the USB OTG bus to the miniPCIe socket (device-mode only) which uses gpio2:
 {{{#!bash
 # export and configure the GPIO as an output high
-echo 2 > /sys/class/gpio/export
-echo out > /sys/class/gpio/gpio2/direction
-echo 1 > /sys/class/gpio/gpio2/value # 0=front-panel 1=miniPCIe-j8
+GPIO=2
+echo $GPIO > /sys/class/gpio/export
+echo out > /sys/class/gpio/gpio$GPIO/direction
+echo 1 > /sys/class/gpio/gpio$GPIO/value # 0=front-panel 1=miniPCIe-J8
 }}}
  * Laguna GW2387/GW2388/GW2391: steer USB OTG bus to miniPCIe socket (device mode only) which uses gpio 5:
