Great!  Thanks for testing and reporting back.  Could you please post
this information to the usb_modeswitch "Device Information" forum at
so that Josh can include this config in the next release?

I'll prepare patches for the option and qmi_wwan drivers. The Windows
driver does some strange and unexpected things, but I am now pretty sure
the firmware supports a "normal" QMI wwan function.
