Resolved Question

USB Hub Individual Port Power Management?

by Apr 9, 2013 11:57PM PDT

I have not found anything on this subject, nor have I had much success with finding a hub that I need; I'm not sure it's possible at this point.

I need the ability to programmatically turn a USB port on a hub on or off. I know there are hubs that allow you to control the voltage that a port is putting out. I also know there are USB strips that have physical I/O switches on each port. However, I need to be able to switch ports on or off from a remote location.

Any help is much appreciated, thanks in advance!

Dead end it seems.

Since such control is not a sure thing and highly dependent on the PC's design, that's why your research hit a brick wall. When I needed such things I had to design the circuits or use other devices. So with this out of the way, did you want to tell more?

PS. Turning on/off things over the internet.

Hmm...

I could see why this would be fully dependent on a PC's design if I were looking to shut down a USB port on the PC. However, I'm not looking to necessarily control the PC's USB port power. I want to control a hub's port power. It seems to me that this idea is so incredibly simple, yet it doesn't exist.

Tipping my hand.

I was and still am involved with automatic testing systems and you can come up with ideas like this one after another. The PC design is what it is. If we need more we go get a box or wire up the circuit, write the code, etc.

I am encountering some newer folk that think "they should have."

If you want more ready to use boxes we can go looking.

I believe that answers my question. Thanks Bob.
