Thanks!
here's a explanation what's going on with the multiple port and usb definitions:
The WNDR4700 has two different USB solutions. A DesignWare DWC2 IP-Core
in the APM82181-SoC ("usb1") which is wired to the SD-Card reader and needs
to be ignored (as it's always connected). And a dedicated Renesas uPD720202
usb 3.0 chip which powers both physical USB 3.0 ports (port1 and port2).
The uPD720202 has two root hubs. In case of the WNDR4700 these are enumerated
as "usb2" (for USB 1.x/2.0 devices) and "usb3" (soley for USB 3.0+ devices).
Hence in order to fully detect any usb 1.x/2.0 or usb 3.0 device being
plugged in to any of the two ports, the usbport trigger needs to check both
ports on the "usb2" and "usb3" root hubs.
