Log Message:
Pull up following revision(s) (requested by bouyer in ticket #544):

        sys/dev/usb/ugen.c: revision 1.148

reading usbdi.c it looks like usbd_get_config_descriptor() can actually
return NULL, so check for this.

I got NULL pointer dereference here with a device showing:
[   303.732632] ugen0: autoconfiguration error: setting configuration index 0 failed
