 Dang, I should have thought of including that.
 
 It's too late now the E173 just passed through my lab for a few
 hours and it probably won't be back in the forseeable future.
 
 Without any patches it comes up with the E173_INIT product-id and
 da0/cd0 attaches.
 
 The HUAWEI_INIT mode just hangs the device, nothing happens or
 attaches afterwards.
 
 With the HUAWEI_INITSCSI it disaspears, then comes back with the E173
 product-id, da0/cd0 attaches, but umodem for some reason does not.
 
 The patch makes umodem find it, but as three separate devices,
 not as one device with three subdevices.
