Thereis no /dev/cdc-wdm0 with the cdc_ncm driver. But you don't need it. The huawei_cdc_ncm variant of cdc-wdmX is just an additional AT command channel. You can use any serial AT command channel instead. Maybe /dev/ttyUSB0?
Haven't looked, but maybe our scripts ties the handling of these devices to the huawei_cdc_ncm driver? Maybe they don't understand that the cdc_ncm session can be controlled by AT commands? There probably hasn't been many examples of Huawei devices using the cdc_ncm driver.
