I have built a new PC. I have installed a USB PCI adapter. I have a USB hub linked to one of the extra ports. The HUB is powered by an AC adapter, however, I'm not getting anything working through the hub. I have an RGB mouse and keyboard, a couple of dongles and a lightpack cable hooked into it. Is the hub defective or are you not meant to have a setup like this? I have plugged the hub directly into the motherboard and get the same results. Any help would be much appreciated.
