Thanks.  Sounds more and more as if we should just disable #11 in the
driver for now, like we've done with #20 for the 68a2 devices.

Well, that could still be caused by a "data format" mismatch on
interface #8.  You could try playing with the CTL_SET_DATA_FORMAT there
to see if if makes any difference.

Does anyone know if there is any public documentation for the QMI_WDA
service? It would sure be nice to have... 

There is also the QMI_CTL_SET_INSTANCE_ID request, which I'm not sure
we've fully understood how to use for these multi-QMI devices.  They
might require a different instance ID for each QMI channel?
