I have a home built PC that I put together this spring and have no problems with it except for the fact that I only have two USB ports. I know it's standard but it would be nice if they could put four or six built in. Anyway, I'd like to add a couple more but would like some advice on the best way to go about it. I have a PCI to USB slot card that I've never used. I bought it for an old PC and never used it. Tried it in this one and can't seem to get it going either. My motherboard is an Abit VH-6 II and has pin connectors for two more USB ports. I picked up a connector with two wires that fed into two USB ports to be put on the back in a free card slot. But again I couldn't get it to work. If I plugged my USB webcam into the built in port it works fine, if I move it to the others it doesn't work I've noticed some USB external ports come with a power adapter and some don't. Also some are high speed and low speed USB and there are other differences as well. I am currently using my two ports for my printer and webcam. I plan on adding a scanner, a game controller or two and maybe a cradle for a PDA and a digital cam card reader. Anyway, I'm hoping someone can understand my post and offer some guidance. Thanks.
