The VM can see all the usb devices. However, I dont have any devices showing up as connected to the EHCI controller on the host, # usbconfig list ugen0.1: <Intel EHCI root HUB> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.1: <Intel EHCI root HUB> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen0.2: <vendor 0x8087 product 0x800a> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.2: <vendor 0x8087 product 0x8002> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) I do have USB-2.0 devices plugged into these onboard controllers. Why are they being connected to the xHCI controller?
