Huawei E1732 qmilib supported?

[Madhan]

hi bjorn,
Is it possible create a character device file by using cdc_ncm alone
(/dev/cdc-ncmx ) ?
By doing so , we might not require sub driver just to send AT commands , we
can send AT commands directly
to the dev file created by cdc-ncm
am i rite Bjorn ?Is it possible ?
