I seem to have some problem with my USB 2 PCI card. I am unable to run certain devices with it. eg. my USB 2.0 anypak portable hdd. however, when i connect the same hdd to my computers motherboard's usb1 port, it works fine. the agent told me it is because of inadequate power. if that is so, how do i power up my pci card. i already go a damn powerful power source for my comp.
