FS#2091 - wrt1900 (v1 mamba) USB 3 port broken

Appears to be a regression on master with no power to USB 3 port on wrt1900, still works on 18.x

FWIW, I've been using arbitrary master revisions on a wrt1900v1 for quite a while without noticing any such issues. I have a single FS USB device plugged into the USB3 port, and do use this device regularily so I am pretty sure I would have noticed it failing. I believe FS and HS devices should behave the same way wrt USB3, so I don't think that difference can explain this working for me.

EDIT: A thought just occured to me: I have never tried hotplugging anything into this USB port. Maybe that is what's broken? My USB device is always plugged in. Could you please provide some more details on how you do the testing?

Right after I opened this FS I flashed a _bot_ generated snapshot and the USB3 port had power with that image. I then reconciled the installed modules of that against my image and nothing stood out as a possible cause.

I am just leaving an old USB thumb drive (1.1??) that has an on-board LED to see power/activity plugged into the USB3 port.

Some data from an image flashed today.
