I just noticed that I had mistakenly written "hostaddr=5" in the initial post. That should have been hostbus=3. But I'll make sure my description is correct again and will close if it turns out not to be. Sorry for the confusion.

One has to explicitly issue device_add host-usb,bus=USBCtrl.0 .... on the monitor, in order for the guest (Win7 in my case) to see those devices.
