Question on powering USB devices off of 5v line on molex connector
So I got the answer back from Aopen that there's no way I can have the USB bus powered off during standby. This forces me to the old way of cutting open the USB cable, cutting the +5v and ground lines on the USB cable, and splicing these into the respective lines on the molex connectors on the mobo so the USB device receives power only when the PC is on. Questions on this:
1. Can I connect 3 seperate USB cords to the same spot of a single molex connector? i.e. I have 3 USB cords that I need to do this with (some devices are not happy being on a hub, otherwise it'd be one cord) and I'm wondering if I need to pick 3 seperate molex connectors or sections on molex connectors to power these correctly? Can all 3 be spliced into one spot on the molex lines?
2. If I can do all into one spot, I'd like to do this via some type of connector, do such things exist? Example: the molex cables terminate on a connector that has inputs for 3 other connectors...something like a 3-to-1 AC power outlet.
4. Is there a better way to do all of this?
