A number of Huawei 3G and LTE modems implement a CDC NCM function, including the necessary functional descriptors, but using a non standard interface layout and class/subclass/protocol codes. These devices can be handled by this driver with only a minor change to the probing logic, allowing a single combined control and data interface. This works because the devices - include a CDC Union descriptor labelling the combined interface as both master and slave, and - have an alternate setting #1 for the bulk endpoints on the combined interface. The 3G/LTE network connection is managed by vendor specific AT commands on a serial function in the same composite device. Handling the managment function is out of the scope of this driver. It will be handled by an appropriate USB serial driver.
