Hello Mauro, Haven't heard back from you in a while. Maybe someone else can point out what I'm doing wrong?

Whatever options I pick for my 3.4 config, CONFIG_DVB_USB_DVBSKY remains unset in v4l/.config $ grep -r DVB_USB_DVBSKY media_build/v4l/ media_build/v4l/Kconfig:config DVB_USB_DVBSKY media_build/v4l/Kconfig.kern: [snip config USB] media_build/v4l/Kconfig.kern: [snip config I2C] media_build/v4l/.myconfig:CONFIG_DVB_USB_DVBSKY := n media_build/v4l/Makefile.media:obj-$(CONFIG_DVB_USB_DVBSKY) += dvb-usb-dvbsky.o media_build/v4l/.config:# CONFIG_DVB_USB_DVBSKY is not set I suppose some prerequisite is missing? Does anything obvious come to mind? I've resorted to interrupting the build and changing v4l/.config to CONFIG_DVB_USB_DVBSKY=m (and the module is correctly built) but this feels like an unnecessary hack.
