In my case I don't disable USB support, insted I selected an USB controller that will not include EHCI, because the main problem reported by de exception was with

VBoxEhciR0.r0 for device 'usb-ehci'

What helped me was to disable the USB support , at the project settings -> under the USB section. Uncheck "Enable USB"

For me, I solved this by activating USB in 1.1 instead of 2.0.

Disabling USB completely also works
