    182    - R241, R242 = Load to route USB to frontpanel connector J19 (top USB port) (default on GW2388-SP208, SP212 and SP213 w/front panel USB loaded)

    215  * Laguna GW2387/GW2388/GW2391: steer USB OTG bus to miniPCIe socket (device mode only) which uses gpio 5:
    216 {{{#!bash

    218 }}}

    241  * Laguna (where the OTG controlleris 'dwc2.0'):
    242 {{{#!bash
    243 echo dwc2.0 > /sys/bus/platform/drivers/dwc2/unbind
    244 sleep 1
    245 echo dwc2.0 > /sys/bus/platform/drivers/dwc2/bind
    246 }}}
    247212
    248213Ports provided by a USB Hub's (will have a '.<port>' in their bus-device.port entry in the table above) with over-current/fault detection such as those found on a GW530x/GW540x/GW630x/GW640x can have their VBUS reset by unbinding their upstream bus-dev (no '.<port>') from the USB bus:
     
    258223 * Note that for USB 3.0 capable devices (Newport) not need to bind/unbind both HS and SS for VBUS to be affected.
    259224 * this is not possible for MiniPCIe sockets as their VBUS comes from the 3.0V rail
    260 
    261 
    262 Ports with GPIO controlled VBUS such as the Laguna boards can be reset by turning them on/off via gpio control:
    263  * GW2382 (gpio9):
    264 {{{#!bash
    265 echo 0 > /sys/class/gpio/gpio9/value # de-assert GW2382 VUSB_EN
    266 sleep 1
    267 echo 1 > /sys/class/gpio/gpio9/value # assert GW2382 VUSB_EN
    268 }}}
    269  * GW2387/GW2388/GW2391 (gpio6):
    270 {{{#!bash
    271 echo 0 > /sys/class/gpio/gpio9/value # de-assert GW2387/GW2388/GW2391 VUSB_EN
    272 sleep 1
    273 echo 1 > /sys/class/gpio/gpio9/value # assert  GW2387/GW2388/GW2391 VUSB_EN
    274 }}}
