+Ports 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:
+ * Examples:
+  - GW640x SS:
 {{{#!bash
 echo 2-1 > /sys/bus/usb/drivers/usb/unbind
 sleep 1
 echo 2-1 > /sys/bus/usb/drivers/usb/bind

 }}}
  * this is not possible for MiniPCIe sockets as their VBUS comes from the 3.0V rail
