Keyboard, Trackpad, and USB unresponsive on ANSI PBP

Assuming the other OS on the micro SD is fine (which I would expect it is) I'd assume something went wrong with the manjaro install and start over there.

If you have already tried other distributions on the sd card and are getting booting,  but no usb,  (the keyboard and trackpad are usb devices, actually) it may indeed be hardware. 
Can you ssh into the device?  (the wifi adapter is unfortunately also a usb device,  but you could also use an external ethernet adapter to make a wired connection,  should it not be working.) You should should be able to look at dmesg to see if you can see usb problems,  or run lsusb,    Do you have a serial cable?  If so,  you could attempt to watch the machine u-boot messages. 

with no external usb devices, running on Manjaro, I see this from lsusb:
