I recently went through a similar experience.
I think the "NEC PCI to USB Enhanced Host Controller(B1)" is the USB 2.
Mine was a VIA brand, but said "VIA USB Enhanced Host Controller".
After removing *all* USB devices and rebooting, it changed.
Now it's "VIA USB 2.0 Enhanced Host Controller", and works fine.
For some reason, you need to force USB driver reinstall after adding the
hardware.
