Mark,



Black, white and green are common for wall outlets. Often a red wire is

also used. In these cases the red wire is also a "hot" wire and it's

switchable. With a dual wall outlet, one outlet is always on and the other

outlet is controlled by a switch.

Not sure whether you can make one of the outlets in yout USB/wall outlet

switchable. That should be covered in the direction sheet. If not tape off

the red wire and just use black white and green.

Agree. The way you make a typical receptacle into the split kind
is to break off a tab for that purpose between the two sections. In
the case of a USB outlet, if it's made like that, which half is wired
lived likely matters, because something has to power the USB.
