Hi,
After applying Oskari 's NCM patches, I could get my E3276 work.
That's the log of using NCM protocol to set WAN connections.

I hope that patch could merged to Openwrt mainstream to support NCM

主题: [OpenWrt-Devel] [PATCH] [packages] ncm: add packages for ncm protocol
support and driver/at-command set for huawei e3276 dongle
This patch adds 2 packages. A package for NCM protocol with modular support
for drivers/at-command sets. Second package adds support/driver/AT-command
set for Huawei E3276 dongle. This package can also easily be used as a base
when creating support for another dongles.
