Okay so, I have a device that has one usb port. This port only has enough power for one of my usb devices at a time. I would like to get a splitter to support two usb devices. However is it possible to choose where the power goes at any given time using programming? (Eg. send power to usb device A for 5 seconds and then switch to sending power to usb device B for 5 seconds, etc.). Perhaps my question is moot: if I got a normal splitter, would this work fine anyway?
