Ok I'm needing some help with a project. I'm trying to add 1 or 2 more USB ports internally to my Toshiba A105. I've looked up stuff on the internet but the one I found uses an existing USB and you just solder wires to it with your device of choice. It makes that USB port you solder to unusable to any other USB devices so you'd only be able to use it for your internal USB device. On my device manager I have 5 usb root hubs and 4 actual USB ports on the computer but i need help finding the internal 5th one so i can solder some wires to do my mod. If anyones done something like this or can help please respond.
