Motherboard capability question - Pinholes for dual USB port, but only single used


On this old motherboard I have, that is now being used in a computer I rebuilt, has pin holes for a dual USB port, but there is only a single USB port installed...

I'm wondering if I can install a dual USB port and have it work, because that would be very good.

What do you mean by pinholes? I assume you mean a header. Many motherboards have USB port(s) on the motherboard that stick out the back and cables that plug into the motherboard for USB connectors on the frontside of the computer case.

Define old. If this is a really old motherboard you might only have USB 1.0 ports and so I would get a PCI USB 2.0 card.

I mean points where you can solder pins in from a port. That is what I mean by pinhole. Pins being the pins on the USB port that are to be soldered.

they were no doubt put there as an option it's most likely you don't have the right chip set to support another port on the mother board
BUT all is not lost
external usb hubs are cheap and totally transparent
some can power much larger loads than a built in port
you just daisy chain them to the one port you have

Yeah, I went ahead and tried it. Didn't work, so I did what Rob.rice kind of suggested (albeit before I read his suggestion), and soldered the leads from a USB hub to the former location of the one USB port I did have. Then, I used a female connector to replace the port I removed from the board, and fed it back to the hub, and also made a harness and connected the other 2 ports to the hub.

All is well now.

Actually, all is 95% well. I can plug and detect 3 USB drives, 2 and a keyboard, etc etc... USB drives and keyboards are fine, a printer is fine, and presumably the rest would be fine, too... BUT..

A USB mouse won't work (doesn't get detected, or powered on. By examining the CPU load, I can see a spike where detection was attempted) without a USB keyboard plugged in. Wrap your head around that one...

Hi,

The load for the 'hub' which you added may exceed the capabilities of the port that was soldered to. Look at the motherboard specs for the on-board hub load capabilities.
