Running HEAD-11.

I have a Zopo Z980+ running 4.2.2.  I see this when I plug it in:

This trace corresponds to the internal and external storage.

After enabling USB storage on the phone I can mount the internal
storage, but not the external storage.

You have to be sure that USB debugging is turned off in the
developer options.  These may not even be visible on your
device because Google hid them at around 4.2.

I suspect that you just need some quirks to support the device.
