Yeah sounds like you just need a relay that switches at 3.5v or whatever USB is

You could find a relay that uses USB voltage for the coil power and make what you need with a spare power strip and some time.

USB powered 110v relay
I was looking for a kit or other "things" to build my own "USB powered 110v switch" and ran across this website.
I know many here are more versed with this kind of thing an wanted your opinion on building my own or any other solutions that might exist.
Conceptually, I want 110v power to be switched on when the USB is energized.Tags: None
