The host is running on an NVidia card. Neither i915 nor xhci-hcd is loaded as kernel modules.

The USB3 succeeds import. The Intel GFX creates a crash on Windows 7 boot.

Have not found any clear instructions to how to assign guest device PCI-ID's, so just took two examples as found in the advanced settings documents.

Tips and/or workarounds appreciated. 

Attaching virtualbox logs.
