I have a PCI expension card with 5 USB 2.0 ports with VIA VT6212L chip that I'd like to use with my PC.
After installing the card into the free PCI slot the PC boots up perfectly. The USB ports on the card work as they should. However, the problem is when shutting down the PC. After Windows has shut down, the PC won't power off. The keyboard and mouse LEDs go off suggesting that the USB ports on the motherboard have been powered off, but the PSU fan, CPU fan and case fans keep running indefinitely. In order for the PC to power down completely, I have to hold the power button for several seconds.
Someone suggested I look at the wakeup settings in the BIOS, so I have messed around with them a bit. Normally, I keep the "Wakeup by USB" setting set to Enabled, so that I can wake the PC from sleep just by pressing a key on the keyboard. The interesting thing is, if I set "Wakeup by USB" to Disabled, the PC will power down properly also with the PCI card installed. The downside is that I am not able to wake the PC from sleep by touching the keyboard or mouse, so I don't consider this a solution.
It's like there is somehow an active USB device plugged into the card, constantly waking up/preventing the PC from powering down (even if all the USB ports on the card are empty).
Another interesting thing is that the "Wakeup by PCI" setting was already set to Disabled. Yet somehow the PCI card still seems to be waking up/preventing the PC from powering down.
Could anyone more knowledgeable help me out with this?
