Folks - Does anyone know if it's possible to remove power from a USB interface under control of the computer? Or if it's even possible under the specs of the interface? Like, might there be some assembly that could do this?
TIA!

As in, you want your peripheral connected to the computer but don't want any power going to it?
The 4 pins on a USB wire are power, 2 data, and ground. You could figure out which one is power and cut that wire, but I'm not sure if the USB interface will still work if you do that.

What I'm interested in is whether I can have the power removed under control of the computer. (I guess if I simply wanted to remove power, I'd just unplug it, right?)

That's a very good question, but I think you're in the wrong place. I would speculate that it varies from implementation to implementation. Try a hardware or developer's group.
