Details - At least in WRT1900ACS but it could be in another Linksys WRT AC series the USB led names are wrong. The device has USB1 and USB2 leds, but in the default configuration USB2 and USB3 are set up.

I don't know if USB2 should be USB1 and USB3 should be USB2, or only USB3 must be renamed to USB1.

Will try to make sure what of the two possible changes is the correct one and then comment it here.
