Update the net usb qmi_wwan driver to support Longsung U8300/U9300. Enabling DTR on this modem was necessary to ensure stable operation. For U8300 Interface 4 is used by for QMI interface in stock firmware of U8300, the router which uses U8300 modem. Free the interface up, to rebind it to qmi_wwan driver. Interface 5 is used by for ADB interface in stock firmware of U8300, the router which uses U8300 modem. Free the interface up. The proper configuration is: Interface mapping is: 0: unknown (Debug), 1: AT (Modem), 2: AT, 3: PPP (NDIS / Pipe), 4: QMI, 5: ADB T: Bus=05 Lev=01 Prnt=03 Port=02 Cnt=01 Dev#= 4 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1c9e ProdID=9b05 Rev=03.18 S: Manufacturer=Android S: Product=Android C: #Ifs= 6 Cfg#= 1 Atr=80 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
