Hi, I just bought a 4-port USB 2.0 controller with the intent to plug it in the PCI bus of my Ultra 5. Unfortunately, once it's plugged in, the machine doesn't even reach the OBP prompt and the screen remains off. The controller is nameless (the card reads "CK-0001C", though), with a VIA VT6212L chipset. Does anyone have an idea how to diagnose the problem? Did anyone succeed with this or another USB controller in an Ultra? Thanks, Ludovic.
