Background:
My dad has a Compaq Presario 7110US and has an 8GB USB drive to back up all of his data, his only problem is the speed of the ports on the front of his computer. So I suggest he gets a USB2.0 PCI card and then we can get a cable to attach to the front panel USB ports. After figuring out yesterday that the motherboard is proprietary (of course I expected this from Compaq) and I was unable to find any type of documentation for the motherboard. So today I broke out my multimeter and the front panel ports I figured out the correct pinout for the headers on the little front panel circuit board. Since I already have a USB2.0 PCI card and a cable to connect an internal media card reader I took those devices out of my computer and put them in his to test all of this before I have him purchase anything. I was only able to wire up one of the ports after adjusting the cable.
Now to the problem:
I hooked the front panel back up and plugged it into the internal port of the PCI card. When I plug in a flash drive it does not read it at all. If I unplug the cable on the inside and plug it intot he bac of the computer, so that the front panel is connected to USB1.0 it works fine. The only things that work when the front panel is connected to the internal PCI card are his wireless mouse and the printer (did test pages on both the 2.0 adn 1.0 interfaces through the front panel). The only thing that I can think of that is happening is that it's not getting enough current to drive the device through the 2.0 interface, which then confuses me because it works fine through the 1.0 interface.
Sorry for the long post, but does anyone have any ideas? Do I maybe have to make sure both of the front panel ports are wired up? I was only able to wire one of them because of the cable I have and the fact that my PCI card only has one internal USB port.
