Declaring a usbdevice_name while we still have an explicit call to
usb_host_device_open in vl.c causes usb_host_device_open to get called
twice if the initial call fails.

Wrong way around, the vl.c call should be zapped instead.  Just did.

Sounds good to me, but you will also need to fix usb-bsd to
declare a usbdevice_name and initfn then.
