Hi Zoran,

Thanks, I modified the Makefile:

obj-m := huawei_cdc_ncm.o
Kconfig (obj-y := huawei_cdc_ncm.o)
SRC := $(shell pwd)
all:
$(MAKE) -C $(KERNEL_SRC) M=$(SRC)
modules_install:
$(MAKE) -C $(KERNEL_SRC) M=$(SRC) modules_install
clean:
rm -f *.o *~ core .depend .*.cmd *.ko *.mod.c
rm -f Module.markers Module.symvers modules.order
rm -rf .tmp_versions Modules.symvers

but this is the error:

ERROR: huawei-1.1-r0 do_configure: oe_runmake failed
