ipq806x: non-working USB 3.0 port on R7500 / Netgear X4 nighthawk
Username: Thomas Reifferscheid

Device problem occurs on all lede versions. It’s known to be working with the stock linux kernel-3.4.104
The 2nd USB 3.0 port is not working at all and you can read from dmesg as follows:
[ 74.689113] usb usb2-port1: connect-debounce failed
Instead connecting a USB 2. drive to USB port 2: [ 162.744896] usb usb2-port1: connect-debounce failed
Connecting it again: [ 3867.976984] xhci-hcd xhci-hcd.0.auto: Cannot set link state. [ 3867.977104] usb usb2-port1: cannot disable (err = -32)
I can confirm +5V vs. GND voltage when observing it.
