I don't really know. This is the second time lately that unncessary
"add device to driver" action from usb_modeswitch has come up. It
wouldn't have been so much of a problem if it weren't for the fact that
this hides the QMI function from the qmi_wwan driver. I wish
usb_modeswitch would stop doing that. But it is a very good thing that
it request reports here.
May I ask what distro you are using? In the other case, the distro
failing was manjaro 15.09. Older or otherwise incomplete usb_modeswitch
data can cause such problems. You should verify that you are using the
latest and greatest usb_modeswitch database (although as I said, this is
a device we've known about for a very long time)
If the problem is with usb_modeswitch in general, then I can only refer
you to the http://www.draisberghof.de/usb_modeswitch/ forums. Unless
Josh is noticing this email thread and replying here...
There isn't really anything we can do on the driver/kernel side. The
device is already known to the drivers supporting it. Adding it again
won't help :)
