Hey guys, I finally got my SATA card to work in my PowerMac, very cool. I have an issue with the USB card. It's a supported NEC chipset, but when I have it installed, one of the USB ports on the PowerBack logic board doesn't work. I changed the slot and it does the same thing, I plugged in a CF card reader and it lights up for a second and then turns off. Any ideas? Both ports work on the NEC card though..
